Some kids just don't sleep through the night until they're older and stop having growth spurts for a while. One of our grandkids didn't sleep through the night until he was at least 4. Every single night he'd wake up and come find us, curl up in bed with us and sleep the rest of the night.
As for the bottle, have you thought about a binky? If he's seeking something to suck then he might need something he can find on his own. Our pediatric dentist told us that the mouth rinses out and drinking a bottle was fine. It's holding a dripping bottle in their mouth that eats the enamel away. The saliva never gets to completely rinse the mouth so the stuff is constantly on the teeth, eating away. If they take a bottle and put it down when they're done it's the same as drinking a glass of liquid. No difference, milk is milk no matter what it comes out of. Just make sure he's not keeping a dripping bottle in his mouth. The pacifier might help with that too. You sure don't want to take the bottle and him find his fingers to suck if it's sucking he is needing.
Nutrition. Is he eating enough calories during the day? Breakfast, snack, lunch, nap, snack, dinner, late snack? If he's truly hungry during the night he might need something more substantial at that late evening snack. More complex carbohydrates and protein instead of easy to burn calories.
I'd also say give him 4 ounces of water each hour to see if he's just thirsting for fluids. See if it helps him during the day too.
If he's taking a 4 hour nap each day that's too long, put him down after lunch and get him up after a couple of hours. If he's too tired the rest of the day and falls asleep after dinner then he might need a little bit longer nap but make sure he's active in the afternoon so he'll be ready for bed later. If he's going to bed at 7 or 8 that might be too early for him too. He might be a 8 hour sleeper and not need 12 hours per day. Our kids all want down for the night at 9.
We have busy lives and it absolutely did not make sense to come home from work, eat dinner and put the kids to bed. What sort of family life is that? Not one. So we did our things in the evenings and then got home around 8-8:30. Eat snacks, baths, bedtime stuff, kids out and down, except that one boy, for the night.
So I think there are things that influence night time success and some of the things we've done with out kiddos have helped. One kiddo it made no difference at all what we did, he didn't need as much sleep as we thought he should have.
