Sleeping through the night is the holy grail of parenting. Charlie didn't start sleeping through the night until 4 1/2 months when we sleep trained. He was a horrible sleeper until then.

I'm really hoping that Olive sleeps through the night on her own because I don't want to sleep train her. Right now she wakes up every 3-4 hours like clockwork, but her adjusted age is only 4 days.

When did your babies start sleeping through the night?
