is dropping in the curves ok then? I don't worry about slowing down so much as he's dropped in % (curve). I definetly don't want a fat baby but between the constipation and the drop in % I was concerned.
I don't think you should worry Julie. Both of my boys dropped significantly and not once did I think it was because they weren't developing properly. I just think that lots of LOs are predispositioned to be small, no matter what their birth weight. I tend to grow larger babies (not huge, but not small, and much bigger than you would expect for a tiny girl!). So because they are a healthy weight at birth, it seems like they've fallen off their curves but really I think that the weights/percentages that they grow into are the 'normal' ones, not their birth ones. Does that make any sense?
I don't know what percentiles they sit in now, but I do know they are both very small, and very healthy.
We have friends whose babies are really tiny at birth, but then become these huge porkers before they're toddlers! I'm sure genetics plays a part as well.
I don't think you're doing anything wrong.
