Your trying , your trying so very hard to get your sister .
Especially if she has any food or a juice bottle.
For 5 months of age you have great head control. Lifting it high of the ground for long periods of time and resting in your arms.
At 5 months and almost 2 weeks you have learnt to roll from your front to back.
You have also learnt you can grab your feet .
it won’t be long baby boy and you’ll be grabbing her !
