My daughter 6 weeks old is breastfed and these past 2 days if she isn't on my boob she's crying all the time, I can't get anything done. And she usually takes naps but yesterday and today she will only sleep when on my boob, I'll put her in her crib but she'll wake up in a matter of minutes just crying so hard she coughs. Could this be a growth or feeding spurt?
