Challenge of infant led BFing at night

[Kmn]

You need to go to bed in the early evening when she does for a few days - it's your best chance for a decent rest.

If she is really sleepy she might be having a growth spurt - usually follows a period of fussiness and ravenous eating. One day it's all eat, eat, cry, eat and the next - zonk. Usually passes in a few days to a week. It's constantly changing at this stage so I second Kmn's advice - roll with it and get your sleep any time or way you can!
