My sweet baby girl is 3 weeks yesterday.. and she is eating constantly and refusing to nap during the day. Yesterday she was up from 8:30 am till about 9pm, she took some cat naps during the day; maybe three 20 min naps... and then I finally got her down at 9pm and she slept so good. But Is this part of a growth spurt? I’m a first time mom so I have no idea, if it wasn’t for this app I would of never known about the 3 week growth spurt.. so any input helps!
