I have a 5m old DD1. She is EBF but has had formula twice before in emergencies. Since she was a newborn she has never slept much in the day and less at night and she would want feeding between every 1-2 hours.
At about 3m old she started going longer at night and would sometimes go up to 5 hours which was amazing, but this only lasted 2 weeks and one were back to every 2 hours on the dot 
The thing is now I'm really starting to struggle with getting up, I just feel shattered all the time. When I feed her during the night, ill tickle her feet, blow her onto her face, wind her and try to just wake her up abit more then latch her on again hoping she will have a good feed and sleep longer but within at least 2 dummy sucks she's sound asleep again. I did use to try and change her nappy in the night but that never worked either.
DP keeps telling me to give her FF because people have told him she will go longer at night but I've been saying no shell sleep when she's ready but now I'm getting desperate. When she's had a bottle of FF she has seemed to go longer between her next feed but I'm not sure if this is a coincident.
Should I give a bottle of FF before bed and hope for the some sleep or does anyone have any other great ideas? Thanks
