4 months old. sleeping lots.

so..my girl has been sleeping alot lately. at night it's 11pm to about 5 or 6am has a bottle sleeps till 10 or 11 wakes up is up for maybe an hour or two before she's ready for a bottle then it's right back to sleep for another 1-2 hours. And again up for an hour then sleeps. some nights she refuses to go to bed. she'll scream and cry unless we're up and walking around with her, then when she gets hungry I'm not allowed to out her down while she has her bottle. I have to sit in a stupidly uncomfortable position for about an hour until I'm sure she's asleep, swap the bottle for her pacifier, and then put her in her bed. last night she did this and was awake for 5 hours just screaming and crying to the point i wanted to scream and cry. any advice?
