I have 6 week old twins and I'm sure one of them has a cows milk intolerance? She's always been unsettled right from birth, i havs them on Aptamil, she was projectile vomiting so we thought reflux, so I have changed her milk to Aptamil anti reflux.. everything was better for a week or so now she's so unsettled again, constipated, has a red spotty rash on her face, a constantly stuffy nose , cries out whilst feeding, stomach gurgles whilst having a bottle.... I've rang gp but they won't give her an appointment as she has her 6 week check next week anyway so he's said to discuss then but she is suffering and so are we 😵💫 I'm wondering is it worth buying the lactose free Aptamil to try? If so how long does it take to settle things down... or should I just carry on and wait until her check. We are tired, she is tired , we are so lucky her twin is so easy going and settled because the poor thing is always having to be laid on her play mat or on her cushion because all things are focused on the unsettled twin. help 🤣 tia x
