my daughter is five weeks and wakes alot in the night. the day before yesterday she had a small top up of formula after the night time feed (around 11pm) which was about 60ml the reason was that i was ill so had to run off to the bathroom for a bit so my husband gave her a little to calm her!. She slept untol about 4:30 which was fantastic - longest rest I have had for ages!.
If we did this every night and only for this feed would it be a problem for the rest of the feeds? would she still happily bf for the rest of the day or would it be a slippery slope. We didnt do it last night and as a result I got 4 hours sleep and now I have spent the whole morning shouting and grumping at the other children lol
