My LO is now 5 months old. Up until her 4 month "birthday" she was an AMAZING sleeper. I'm talking about going to sleep at 8, waking at 3 to simply feed, then back to sleep until 7. Lately she has been going down around 9 and waking up every 2 hours! I find myself leaning over to pop a bottle in her mouth and she falls asleep almost instantly. (She sleeps in a bassinet next to me) any advice on how to stop/survive this? This mama needs to sleep!
