Hi J.! I have a boy that was born July 25th and he's actually starting to do the same thing. I don't know if it's because we've just put one of those fish things that play music in his crib and he's scared of it. But, we've had the routine of bath, bottle and bed at bedtime since he was born. So, he knows it's bedtime, but lately he will just cry as soon as we put him down. I will stand next to his crib until he falls asleep, which is usually about 5 minutes or so. I think it's separation anxiety, normal at that age!
