Wonder weeks and sleep

yepyepsms

I think my daughter is going through a wonder week and I am wondering if that has affected her sleep too. She is 9.5 weeks. We had consistent 4 hr stretches for a couple weeks and have only got 1-2 between wakings the last few days. Don't think it's a growth spurt based on her age and eating habits during the day (plus not all waking at night is eating). And it could just be her being a baby and inconsistent too:)

Just curious, If you are pretty certain you knew when your LO had a leap did you find it changed their sleep too?
