Baby not waving yet, how do I encourage him to?

My baby won’t wave either but she’s learnt how to high 5 this week 😂

Do you wave to them often? I make sure to wave and say hi whenever I get mine out of bed, when I walk into the room she’s in, whenever we see or meet someone new. Then I wave bye whenever I’m leaving or someone else is leaving. Repetition is key

My girl still doesn't wave She's done it maybe once pr twice but we always wave hello and say hi and wave bye snd say bye if someone is coming or goinf
