Reagan is 24 days old. In the past week or so, she has been fussy during and after nursing. I usually hold her, pat her back, bounce, and rock her. Sometimes she nurses more, but, aside from the middle of the night, she generally doesn't nurse to sleep, but seems to prefer bouncing/walking or rocking. She usually has poopy dipes a few times a day, but it has been over 24 hours since she last pooped, possibly verging on 36. She has fusses for close to an hour at times. She has also been spitting up more. Do I need to drop dairy from my diet? I don't know what to do.
