my 9 week old sucks at sleeping and refuses bottles!

Laura
Tired mama here. Feel like I'm doing something wrong or not doing enough! He as of recently has been waking up after 30 minutes thanks to those little 30 minute sleep cycles (not entire night but sometimes from 3am on). 
When your little one wakes up, crying or not-at night, do you feed him or her? Help them get back to sleep ? Let them get back to sleep on their own even if crying?  Since I'm breastfeeding, when my guy wakes up, I typically offer him the boob! He was sleeping good 4-5 hours stretches for about 2 weeks and those have disappeared!! Help! He doesn't self soothe yet. Just started accepting a pacifier last night. 
The bottle is a whole other issue...
