Good evening ladies. I just had my new little one picked up early because she refused to drink for me. She is breastfed, 12 mos and underweight. My daughter is two months younger than her and is 3 lbs heavier! Mom sends pumped milk for her but I can usually only get her to take 1-2 oz a day (8:30am-5:30pm). She can't use sippy on her own and I have to physically hold it for her. Mom does not want to use bottles, says it's regression. I told her that the little one likes my daughter's cups (plastic, BPA free, light weight). She bought others and little one took milk yesterday from them. Today she would not take one sip of anything for me (milk or water). I even tried three different cups. At 3:30, I called Mom and told her that I did not want to be responsible for her daughter being dehydrated (not many wet diapers), and asked her to come get her early. Mom was more than ok with this as the last time she had anything to drink was 6am. She came to get her and we'll try again tomorrow. I'm just fearful that this will continue. If she didn't come early, she would not get home until 6pm and it would be 12 hours of no liquid. Would you be worried? Have you been in this situation? Calling parents to come get her good idea?
