Hi, im looking for some advice really, My little boy was doing really well and managing to sleep through the night for the past week. all of sudden he has started waking at 4am again. iv had to give him a milk feed because water isnt doing anything for him, whereas b4 he settled really well with it. sometimes he wakes crying and then when i pick him up he starts smiling at me. any ideas how i can get him back to sleeping through the night? I havnt changed his daily routine at all.
