My 4 month old daughter will only sleep for 40 mins at a time during the day. She feeds every two hours and after being awake for an hour needs to go back to sleep otherwise becomes overtired and very cranky. Often it can take until midnight to get her finally off to sleep for the night (thankfully she sleeps through until around 7.30am). I can’t tell what she’s screaming about, if it is hunger, tiredness, wind, reflux or something else. She won’t take a bottle, even of EBM and I’m worried she won’t be settled soon as I’m going back to work full time in September and won’t relax with anyone except me. Please help!
