I think it's around 5-6 weeks. But it can depend on what you call a smile too LOL. One nurse told me her daughter came out smiling. I think Tallon gave us his first real smile around 5 weeks. I can't remember. (I didn't even record all his firsts anywhere.. altho if I read the baby buddy archives I could probably find out LOL)

I reckon this whole corrected age thing is a bit of a crock. What if her 'real' EDD was at 37 weeks like Tallon? That's full term. So her corrected age could well be 6 weeks already.

How's Sofia going.. any reaction to the needles? Kayla seems fine. I totally forgot about the new one for that tummy bug. I was suprised when they brought an oral vax over for her to have hehe (informed mother that I am )
