Brooke has no interest in rolling from her tummy to her back (the traditional first roll a baby makes). Instead, when she is on her tummy she kicks her legs and flails her arms (like she is swimming) as she tries to move herself forward. She wants to crawl not roll. Too bad her round belly gets in the way.
On the other hand, when she is on her back ... all she want to do is roll over! She desperately tries to get from her back to her tummy but just cant give herself the final push (again, I think the round belly has an impact here). I mentioned before that I "help" her roll ... when she gets about 1/2 way I give her a little nudge so she can complete the move. This was a problem because she kept puking every time I rolled her over.
Good news ... and bad news. Brooke no longer pukes when I roll her over! Why is that bad news? Because now she farts every time I roll her over. Strange baby ...
Updated Startle Reflex
Babies are born with something called the Moro Reflex. Its an involuntary reflex, also called the "startle reflex" causes a baby to extend the arms, legs, and fingers and arch the back. Think of when you are falling asleep and you jerk awake because you have the sense/feeling of falling ... thats exactly what babies experience. Generally this reflex goes away between 3-6 months. Brooke used to extend her arms and legs straight out when she heard loud noises, or we were placing her in her crib. She has stopped that for the most part, but has started something new in the past 2 days or so.
In this video, it looks like she is posing. She is laying on her changing table and has her left arm behind her head. The funny thing is, this is not a pose :) She has been keeping her left arm behind her head for the past two days or so to "brace" herself. (From what, I dont know). 1/2 way through the video she tries to roll over, so you can see her in action. And then her new version of the startle reflex follows her unsuccessful rolling attempt.
