I have an 11 week baby (born 3 weeks premature) who is exclusively breastfed. She's putting on weight well, poos and poos and has loads of wet nappies so must be well. She has been crying and unsettled since Boxing Day and nothing will calm her apart from being on my breast where she will feed well but will also just hang there and sometimes twist and squirm on 1 side. Have used a dummy but she tends to spit it out. Am exhausted. Is this normal? Any advice? She's my second so my toddler is struggling to get a look in
