I feel strange asking this since I have been a Mom for 21 years, but this babe is so different from the other three. My 3.5 mo. old has suddenlt started nursing every hour during the day and night. We co-sleep so she just hooks herself up for the most part. She just started taking short naps lately too and seems crankier. I was wondering if I should perhaps introduce maybe some banana or a little rice cereal? Not sure if this is related, but she has has very watery, yellow poop since birth but ped. said not to worry.
