Baby shakes his head...

My son does that too. Hes 2 now and does it to tell me "no" but a while back he was just randomly shake his head all weird looking. It didnt look normal and i was concerned a bit because hes taken some spills down the stairs but then he stopped. I think i know what your talking about lol

Definitely normal! It doesn't necessarily mean that he had to pick it up from someone else though, because I never shook my head no in front of my daughter and she did it, and still does. It's just them learning to do something different and they like it. It makes them a little dizzy and it's fun for them. With my daughter, when she did it, I started to say no when she did so she knew what it meant and now when I tell her no, she shakes her head. I am in the process of teaching her yes now and so far all we have is her entire body nodding up and down lol.

My son already does this and he is only 7 months.  Don't worry.

MY son is doing it too. It's something new for them to show off so when given the chance they will. My son has started to do it when we do it ot him as well. He thinks it is the funniest thing ever.

I have known ALOT of kids to do this.  It is completely normal!

My daughter does that too. But when she shakes her head no she will say yes.

 Totally normal! My little one does it!  I think its cute!

I've noticed almost all babies do! My 13 month old started doing it when she was 12 months and doesn't do it as often anymore. The child care center I work at, the 12-18 month olds do it and think it's hilarious. Once one does it, the other 8 or so do it LOL.

nothing to worry about. it's just something he just figured out and he gets attention when he does it so he does it more.

 It's normal.  All mine have done it.  My youngest is 15 months old and he thinks it is hilarious to shake his head no.  He's been doing it since he was about 11 months old.
