My son turned six months old the week of May 19th. Everything is happening so fast (though there are days when I wonder if the night time wakings will ever cease). He'll sleep through the night maybe one or two days out of the week, but the rest of the time he wakes a few times during the night and needs to be soothed back to sleep. It doesn't take much time, no bottle or picking him up, just a few pats on the back is usually all it takes, but it sure takes it toll on me! Anyway, he starting sitting on his own at 5 mos. and now he's up on his hands and knees and rocking. No crawling yet, but it'll be soon.
