Hi first time mum here, my baby is 2 months old at the moment and at about 5 weeks we started her in a bed time routine, bath around 7pm then feed and bed. She will usually sleep from about 8pm until 11pm or sometimes 12pm without waking, then she will wake about every 3 hours during the night. She is 10weeks in 3 days and she has suddenly become quite fussy and won’t go to sleep in the evenings.cod she does fall asleep it’s for about 10 mins and then she will cry a lot!! She did have her first immunisations about a week ago could it be that??. Me and my partner are very tired and don’t understand why she has started to be so fussy in the evenings does anyone have any insight or similar situations? I don’t know if we should be doing anything different?
