I have a 5 month old breastfed baby whose been a brutal sleeper from the get go. She used to stay awake for 7 hour stretches and wouldn't sleep until 11.30pm, we could get up to a 4 hour stretch then she would be in bed with me. Now she's older she's worse, she will not nap for more than half an hour and it's often less. When we put her down in the evening she will wake after max 1.5 hours but this evening she's been up 4 times in 2 hours. She used to be in good form generally like the bad sleep wasn't affecting her mood. I've tried timing wake windows and playing with her schedule but nothing helps. We have started weening and that hasn't improved things. She was taking a bottle of either formula or expressed milk a day but has been refusing the bottle every day for over 2 weeks. I don't want to do any cry it out methods but is it possible that there's actually something wrong with her or is she just one of those babies? I feel like at this stage there's an expectation that I am regaining some level of independence but it's still like being in the newborn trenches
