Ben has gained a FULL POUND since birth. This might be normal, but I was totally surprised and excited to hear that! I can tell that he is starting to fill out his newborn outfits, and just today I noticed that he can't straighten his legs completely in a few of them...crazy that he was totally swimming in them just a week ago. Since Ben is eating so well and gaining weight appropriately, we no longer have to feed him on a specific schedule as we did before, which is great. Just last night he slept for 5 straight hours before waking up to eat! DREAM BABY ;) During the days, I have noticed his hunger increasing. Typically he eats every 3 hours or so, but at times he is eating every 1-2 hours.
As far as alertness goes, Ben has at least 2 periods of time a day where he is VERY alert and awake. He will track things with his eyes and will be startled at sudden loud noises. He can definitely recognize our voices (and I think smells).
Here are Ben's latest stats:
8 lbs and 11.5 oz
Weight - 46th Percentile
Height - 56th Percentile
Head Circumference - 41st Percentile
