My Baby Is Not Waving Bye-Bye at 12 Months
The short answer
Waving bye-bye is a social gesture that typically develops between 9 and 12 months. If your baby is not waving by 12 months, it may be within the normal range if they are showing other social communication skills like pointing, reaching for you, making eye contact, and responding to their name. However, absence of waving combined with other missing social gestures (pointing, showing, clapping) by 12-14 months may be a sign of a communication delay or autism spectrum disorder that should be evaluated.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-9 months
Before babies learn to wave, they develop precursor skills: making eye contact, smiling socially, responding to their name, and imitating facial expressions. Around 6-8 months, babies begin imitating simple actions they see, like banging objects or clapping. Waving bye-bye builds on these imitation skills. You can encourage wave development by waving frequently at your baby, waving their hand for them (hand-over-hand guidance), and making it a fun part of your daily routine. Consistent modeling helps babies learn social gestures.
9-14 months
Most babies begin waving between 9-12 months, though some do not wave consistently until 14 months. Some babies develop an unconventional wave initially (rotating their wrist, opening and closing their fist, or waving backward — toward themselves). These are normal developmental variations that typically self-correct. Waving is one of several social gestures that should emerge during this period, along with clapping, raising arms to be picked up, shaking head "no," and pointing. If your baby has some gestures but not all by 12 months, continue modeling and give them a few more months.
14-18 months
By 14-16 months, most children use several communicative gestures regularly. The CDC lists waving bye-bye as a milestone that should be present by 12 months and considers its absence a potential concern. If your child is 14+ months and is not waving, not pointing, not showing you objects, and has limited other gestures, discuss this with your pediatrician. These missing gestures, especially in combination, are among the earliest signs of autism spectrum disorder. Your pediatrician can perform an M-CHAT screening and refer for a comprehensive developmental evaluation if warranted. Early intervention services for communication delays can begin before a formal diagnosis.
What Should You Do?
When to take action
- Your baby is 10-12 months and waves inconsistently — they are still learning and practicing.
- Your baby waves in an unconventional way (backward, with a fist, or with a delayed response) — this is a normal variation.
- Your baby does not wave but does point, clap, reach for you, make eye contact, and show other social communication skills.
- Your baby is 12 months and does not wave or imitate any gestures despite frequent modeling.
- Your baby is not waving and is also not pointing, clapping, or using other communicative gestures by 12-14 months.
- Your baby does not seem to understand common gestures like waving or reaching out to be picked up.
- Your child is 15+ months with no gestures (no waving, pointing, showing, or reaching), limited eye contact, and does not respond to their name — request urgent developmental evaluation.
- Your child was waving and using gestures but has lost these skills — regression of previously acquired skills requires immediate evaluation.
- You have multiple concerns about your child's social interaction and communication — contact your pediatrician or early intervention program without waiting.

Related Speech Concerns
My Baby Is Not Pointing at Objects at 14 Months
Pointing is an important communication milestone that typically develops between 9 and 14 months. By 14 months, most babies should be pointing to show you things they are interested in (protodeclarative pointing) and pointing to request things they want (protoimperative pointing). Absence of pointing by 14-16 months, especially when combined with other communication delays like lack of eye contact, not responding to name, or not waving, can be an early sign of autism spectrum disorder and should be evaluated.
My Baby Isn't Clapping
Clapping typically develops between 9 and 12 months and is both a fine motor skill and a social milestone - your baby needs the coordination to bring their hands together at midline AND the social motivation to imitate you. Many babies clap closer to their first birthday, and that is perfectly normal.
Baby Not Sharing Attention (No Joint Attention)
Joint attention - the ability to share focus on something with another person - is one of the most important social-communication skills that develops between 9 and 14 months. It includes following someone's point or gaze, pointing to show you something interesting, and looking back and forth between you and an object. This skill is the foundation for language learning and social development.
Baby Not Imitating Sounds
Sound imitation develops gradually - babies typically begin imitating vowel sounds around 4-6 months and consonant sounds by 8-10 months. This skill is a key building block for speech. If your baby is engaging with your voice, babbling on their own, and showing interest in communication, imitation is likely developing even if you haven't noticed it clearly yet.
Accent vs Speech Disorder in Bilingual Toddlers
When toddlers grow up hearing more than one language, they naturally blend sounds, patterns, and accents from both languages. This is normal and healthy, not a speech disorder. A bilingual child may pronounce some sounds differently than monolingual peers because they are learning the sound systems of two languages simultaneously. True speech disorders affect both languages equally, while accent influence appears only in specific sounds borrowed from one language to another.
Ear Fluid Affecting Baby's Speech Development
Chronic or recurrent middle ear fluid (otitis media with effusion) can temporarily reduce hearing by 15 to 40 decibels, which is like hearing through water. During critical periods of language learning, this muffled hearing can impact speech and language development. If your baby has frequent ear infections or persistent fluid, discuss the potential speech impact with your pediatrician.
