My 4 month old has started to wake every 2 hours at night and has become very difficult to settle for night sleep and naps. I've tried everything, read a lot of books. The only way I can get her to sleep is to feed her to sleep and work towards her wake cycles i.e 90 mins. I'm finding this exhausting trying to get her down so often. If I get her down she will only sleep for 30 mins. I tried the easy method and lots of other things but nothing is working. Bf with one bottle of formula at night.
I suppose I'm posting for advice from pure exhaustion.
TIA
