Our littlest monkey just turned five months old. We had some suspicions he would officially reach "moose" status at his doc appointment but I was shocked. He is 24" (5th percentile) and 14.5 lbs (18th percentile). He was nearly as big as we expected. In fact he fell off of his growth curve a little. The doc isn't terribly concerned since you have to look at several months of data to see trending. Hopefully at his next visit in six weeks he will pick up steam a little bit.
At five months he is smiling, laughing, starting to roll side to side and using his hands with increasing success. He can put his own pacifier in his mouth about 50% of the time. He is the most happy, smiley, laid back child I have ever been around. He is content to lay on the floor or sit in the swing for an hour at a time. He is amused by everything and everyone. He has barely a shy bone in his body.
Sleep changes from week to week. Just about the time he gets sleeping close to eight hours we will hit a spell of sleeping in only four hour spurts. But he generally eats and goes right back to sleep so I can hardly complain.
Eating continues to go well. I am still nursing him and he is a breast feeding rock star. He eats quickly and efficiently. We started rice cereal at 4 months and have since added applesauce, pears, sweet potatoes, squash and bananas to his repertoire. Being able to eat food has made Jack and even happier baby.
