My LO is 3.5 months (she turns four this week) and was exclusively breastfed until she was 3 months. I started work so we moved her to formula gradually over the course of a month. She used to wake up once during the night for a NF and gradually started eating less so one evening I tried giving her the pacifier instead of a feed and she took it and slept till 7am (her actual waking time!). This happened for a good week. Now for the past four days it has all changed, she wakes up around 4am and I give her the pacifier. She goes back to sleep but then it falls out 15-20 mins later and starts crying so I go in and give it to her again. This continues until 7am when I wake her up to start her day and give her the first feed.
Any idea what's going on? Am I doing something wrong - has the pacifier now become a prop? Or is she actually hungry and I should try giving her a feed? I am scared to give her a feed and she doesn't really want it and then I start a cycle of NFs again.
HELP!!
