I've just started implementing the PU/PD method so that my LO will sleep longer. 3 hours is a longth stretch. Later in the morning, it's evey 15 min he wakes up and I have to stick a bottle into his mouth, only to eat an ounce. (I know,,,wose accidental parenting). I just wanted to know, how long is too long? What is the usual length of time you girls have waited before giving in to a bottle? He uses the bottle to put himself back to sleep--it's his favorite soother. The first time I did it was 15 min, the second time 5 mnutes. I just feel so bad--he cries like he did after his immune shots. He's such a good baby--he never cries during the day, not for fatigue, hunger, boredom, nothing, so to hear him cry like this at night just tears me apart. When a baby is crying 5 minutes feels like an hour so wanted to judge for myself the line between letting him get out some frustration and learn a new habit vs borderline abuse for him. Seriously, the longest he's ever cried in his life (he's 5 months now) was 40 minutes 5 hours after his first set of immune shots. Besides that, he really never cries, just whines. I'm just sooo tired.....after 5 months of this....the nights are hell.
