So, for the past 3 or 4 days LO has been sleeping a TON, like a newborn again. She has also picked up an extra night feeding and has increased from eating 5 oz to 6ish. Instead of sleeping from 6:30-7 to 4-5, shes been waking up at around 2 to eat. She's only 10 weeks... Can this be her 3 month growth spurt already? She is only 10 weeks old...
