so he's doing raspberries now. it's hilarious. sometimes he starts right after he wakes up from a nap or instantly after he eats he'll start blowing. it's pretty entertaining.
on another note...i took him for his 4 month check-up. he was a couple days shy of being 4 and a half months and i don't know if they adjust the percentiles for that, but here are the stats. and yes, we have a big boy...but to be honest, i couldn't ask for anything more!
weight: 16.5 lbs (88th percentile)
height: 25 1/2 inches (84th percentile)
head: 43 cm (79th percentile)
