Is there any hope for me? 😂 my almost 5 month old has his bath at 6 and last bottle at 7 then is always fast asleep by 7.30 and there's nothing I can do to keep him awake, he then wakes up between 12 and 3 and has his bottle then wakes up at 5am for good, might take a bottle, sometimes doesn't, and will refuse to go back to sleep, yesterday morning we was up and downstairs by 4am, is there anyway I can get him to sleep in just a little longer
