Hello! Here's my whole story...
At around a month and a half we noticed he had a light case of reflux so we decided that at night I would keep him in a "standing" position for 15-20 minutes before putting him down. By the end of the 15 minutes, he'd be asleep in my arms. There'd be no rocking, just light pats on the back. Now at 5 months old, I still leave him in a standing position before putting him down, but only for about 10 minutes and he's usually awake by the time I put him down. He'll "talk" and play for 15-20 minutes and then fall asleep on his own. On a very RARE occasion, he'll cry on and off for those 15 minutes and then fall asleep on his own. Only once have I had to go in after 15 minutes and pat him and shush him because he was ED OFF crying his lungs out.
For the naps, I used to swaddle him up to 1 week ago. I would look out for the signs that he was tired (usually yawning or fussiness), swaddle him, give him his pacifier, pat him for about 1 minute to soothe him, put him down (still awake) and place a burp cloth or something similar next to the pacifier so that it wouldn't fall out before he was fully asleep. After a while he'd be so asleep that he'd drop it. When he started waking up during the naps, at first I would go in immediatly and give him the pacifier and pat him for a few minutes so that he'd fall back asleep. It usually worked but after a few weeks I started getting the feeling that he knew I'd be going in and he didn't make the effort to fall back asleep on his own. There'd be days that I'd have to go in 10 times in those 2.5-3 hours but he'd fall back asleep. And then there were other days where he'd sleep perfectly without waking up.
Now that'd he's off the swaddle, I look out for the signs, give him his pacifier, put him down but I have to stay there for a few minutes to make sure he doesn't grab the pacifier because he'll start crying. It's what soothes him. The first few days without the swaddle, he'd wake up after 40-45 minutes and I'd let him cry for 15 minutes before going in to give him the pacifier and patting him. On occasions he'd fall asleep on his own in those 15 minutes. If he didn't fall asleep on his own, I'd go in, give him the pacifier, pat him and once he was calm again, I'd leave the room. If he started crying again, I'd wait 10 minutes before going back in and doing the same and usually that'd be enough for him to fall asleep again. But for the past few days he'll wake up after 40-45 minutes and WON'T go back to sleep.
This is our day:
7:15-8 am: Wakes up. If he wakes up before 8, I leave him in his crib where he's chatting and playing on his own.
8 am: first bottle
8:15-9 am: activity time
9 am: we drop off big sister at summer camp but come home to more activity time
9:45-10 am: put him down for first nap. I've been leaving him in his crib until 12 pm even when he wakes up after 40 minutes and I have to go in to help him fall back asleep.
12 pm: second bottle
1 pm: pick sister up and a little activity time
2 pm: second nap
2:40 pm: wakes up
2:40-4 pm: activity time
4pm: third bottle
4:20-5:30 pm: activity time
5:30 pm: third nap (usually on the stroller or in my arms because we are almost never home in the afternoons)
6 pm: wakes up
7:15 pm: bath time
7:30 pm: bottle
8 pm: asleep
Three out of the seven nights of the week he wakes up in the middle of the night (around 3 am), he'll talk or play with his hand for 10-15 minutes but falls back asleep on his own. I haven't had to go in for about 1.5-2 months now.
I don't know if I gave waaaay too many details but I wanted to be as specific as possible. I know that as babies grow, they'll start sleeping less, but it was a dramatic change. Two weeks ago he was sleeping 2-2.5 hours in the morning. Now he only wants 40-45 minutes. Should I be doing something differently? Or is this normal? Should I keep on trying to put him back to sleep or should I just take him out of his crib when he wakes up? With my first child, the second she'd wake up I'd think: she's not sleepy anymore, and bring her out. But many days she was cranky. I don't want to make those mistakes again, that's why I insist on him falling back asleep.
