Well, your baby's. I don't imagine you remember yours.
Last night DS2 was awake for a total of 4.5 hours. The same as the night before. It's difficult to resettle him, even after a feed (EBF). He wakes easily 4-6 times between 11pm and 7am and it's been like this for the last month.
I'm not sure if I should feed him or try to withold feeds if less than 3 hours because it could be that he is uncomfortable with all that milk shwooshing about inside. He has reflux - I don't know if this is a contributing factor.
I know I'm not the only one. If you've survived the four month sleep regression, please cheer me up and say it sorts itself out quickly enough. If you're suffering through it, tell me your tricks.
