Why NOT set the precedent that if she's scared, hungry, or in pain that you'd come running in the middle of the night? If YOU woke up screaming in fear or pain wouldn't you want your husband to come running? Or would you want him to tell you to get over it and deal with it? Also, if you woke up starving, wouldn't you go get something to eat? Did you ever snack at night when preggers? Babies are growing a LOT more than pregnant women... but for some reason it's okay to not feed a baby, but if someone told a pregnant woman she wasn't allowed to eat now... all hail would break out. Ditto, what would you do if you had a blinding headache or an attack of diarrhea? Just stay in bed and be miserable? You are your baby's arms and legs and brain right now. She CAN'T just get out of bed and go take care of the problem. That's what parents are for.
Just sayin' ... if you would eat, take tylenol, or want a hug after a terrifying nightmare (say you dreamed of your baby being stolen/murdered)... why is it unreasonable for your baby to have food, medicine, or comfort?
