I have 2 questions:
Baby is almost 12 weeks old. had been on a 3 hours schedule.
Issue 1: he used to be a great napper, easy to put down (i just had to hold him for a few minutes and he would fall asleep on his own) but now I have to do shh/pat for 10-20mins and he wakes up after 45 mins.

am i gonna be doing this forever.
Issue 2: His usual bedtime is 6:30 (typically sleeps by 7:30 after settling), this is his 6 hours stretch, I do give him a dream feed, although I do not think it helps. He wakes up anywhere from 12-2am for his night feeding. How can I move his 6 hour stretch? I have a toddler who sleeps at 8, and by the time we go to bed after the dream feed is 10:30pm. I hardly get any sleep, since the baby sometimes wake up at 5:30am.
Please please helps. Any ideas?
