Editorial policy

Toddlerhood is full of big transitions — from cribs to beds, bottles to cups, diapers to potty, and home to daycare. Each change can feel monumental to a child who thrives on predictability. With preparation and patience, you can help your toddler navigate these milestones smoothly.

Key takeaways

  • Tackle one major transition at a time — space changes by at least 2-4 weeks
  • Preparation and gradual introduction reduce resistance
  • Some regression during transitions is normal and temporary
  • Let your child participate in the transition when possible (choosing new cup, picking bedding)
  • There is no universal right age for most transitions — readiness matters more

Crib to toddler bed

When to transition:

  • Child is climbing out of the crib (safety concern)
  • Child is at or near 35 inches tall
  • Child is 2.5-3 years old (later transitions typically go smoother)
  • You need the crib for a new baby (transition well before the baby arrives)

How to make it go smoothly:

  • Let your child help pick new bedding or a special pillow
  • Use a toddler bed or place mattress on the floor initially (reduces fall risk)
  • Use a bed rail for safety
  • Keep the bedtime routine identical — only the bed changes
  • Childproof the entire bedroom (they can now get up freely)
  • Use a toddler clock (“okay-to-wake” clock) to set boundaries about getting up
  • Expect some testing of the new freedom — calmly return them to bed without engagement

Common challenges:

  • Getting out of bed repeatedly (respond with boring, brief returns)
  • Difficulty falling asleep (the novelty wears off within 1-2 weeks)
  • Early morning waking (okay-to-wake clock helps)

Bottle to cup

When to transition:

  • AAP recommends weaning from bottles by 12-15 months
  • Prolonged bottle use increases risk of dental caries and iron deficiency
  • Start introducing cups at 6-9 months alongside bottles

Step-by-step approach:

  1. Introduce an open cup or straw cup with water during meals (6-9 months)
  2. Replace the easiest bottle first (typically mid-day meal)
  3. Replace one bottle per week
  4. Eliminate the morning bottle next
  5. Save the bedtime bottle for last (highest emotional attachment)
  6. Replace bedtime bottle with a cup of milk during the bedtime routine, then brush teeth

Tips:

  • Let your child pick a special “big kid” cup
  • Offer milk in cups and only water in bottles (makes cups more appealing)
  • Never put bottles in the crib or bed (dental risk)
  • Do not dilute bottle milk — this can lead to inadequate nutrition
  • Accept some temporary decrease in milk intake during the transition

Pacifier weaning

When to wean:

  • AAP recommends weaning by age 2 to prevent dental malocclusion
  • The American Academy of Pediatric Dentistry recommends stopping by age 3 at the latest
  • Earlier weaning (12-18 months) is often easier due to less emotional attachment

Gradual approach (recommended for most):

  1. Restrict to nap and bedtime only (no daytime use)
  2. After 1-2 weeks, eliminate nap use
  3. Finally, eliminate at bedtime
  4. Offer a replacement comfort object (stuffed animal, blanket)

Cold turkey approach (works for some):

  • Choose a day and remove all pacifiers
  • Some families use a narrative (“pacifier fairy” or giving to a new baby)
  • Expect 2-3 difficult nights then rapid adjustment
  • Do not go back and forth — once gone, stay gone

Starting daycare or preschool

Before starting:

  • Visit the new space together — let your child explore while you are present
  • Read books about going to school/daycare
  • Practice short separations with other trusted caregivers
  • Talk positively but honestly about what will happen
  • Establish the new wake-up routine 1-2 weeks before start date

During the transition:

  • Create a brief, predictable goodbye ritual (kiss, hug, wave at window)
  • Never sneak away — this erodes trust and increases anxiety
  • Keep goodbyes short and confident (your anxiety is contagious)
  • Bring a comfort item from home (family photo, lovey, parent's scarf)
  • Pick up at the same time daily when possible
  • Expect some regression (sleep, clinginess, tantrums) for 2-4 weeks

How long adjustment takes:

  • Most toddlers adjust within 2-4 weeks
  • Crying at drop-off may continue even after adjustment (but usually stops within minutes)
  • Ask caregivers how quickly your child calms after you leave
  • Consult your pediatrician if distress is severe and unrelenting after 4-6 weeks

Welcoming a new sibling

  • Tell your toddler about the baby in simple terms during the third trimester
  • Read books about being a big sibling
  • Do not make other major transitions (crib, potty) right before or after the baby arrives
  • Give your toddler a “job” with the new baby (bringing diapers, singing to baby)
  • Maintain one-on-one time with your toddler daily, even just 15 minutes
  • Expect regression (baby talk, clinginess, potty accidents) — respond with empathy
  • Avoid saying “you are a big kid now” as a reason to stop comforting behaviors
  • Let your toddler have mixed feelings — it is okay to love the baby AND be angry about changes

General principles for all transitions

  • One at a time: Never start two major transitions simultaneously
  • Prepare in advance: Talk about what is coming in simple, positive language
  • Involve your child: Let them participate in decisions (choosing new cup, new bedding)
  • Maintain other routines: Keep everything else as consistent as possible
  • Expect regression: Temporary backsliding is normal and not a failure
  • Do not go back and forth: Once you commit to a transition, follow through
  • Avoid bad timing: Do not start during illness, travel, or another stressful event
  • Celebrate progress: Acknowledge your child's effort and growth

Frequently asked questions

When should I move my toddler from crib to bed?
The AAP recommends keeping children in a crib until they are climbing out or reach 35 inches tall. Most children transition between 18-36 months, but there is no rush if the crib is still working safely. Later transitions (closer to age 3) tend to go more smoothly.
How do I wean my toddler from the bottle?
The AAP recommends weaning from bottles by 12-15 months to prevent dental problems and excess calorie intake. Introduce cups at 6-9 months, gradually replace bottles with cups starting with the easiest meal, and eliminate the bedtime bottle last.
When should a toddler stop using a pacifier?
The AAP recommends weaning from the pacifier by age 2 to prevent dental issues. Gradual reduction (limiting to naps/bedtime first) tends to be less traumatic than cold turkey for most children.
Should I make multiple transitions at once or one at a time?
One at a time whenever possible. Each transition requires cognitive and emotional energy. Space major changes by at least 2-4 weeks. Never start a new transition during illness, travel, or another stressor.
My toddler is starting daycare. How can I help?
Visit the daycare together before starting, do short practice separations, create a goodbye ritual, bring a comfort item from home, and keep pickups predictable. Most toddlers adjust within 2-4 weeks.

Bottom line

Major transitions are a normal part of toddlerhood. The keys to success are tackling one change at a time, preparing your child in advance, following through once you start, and accepting temporary regression as part of the process. There is no universal right age for most transitions — your child's readiness matters more than the calendar.

Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
