my ds was born 9lb 14 and has continued to gain weight steadily over past 6 weeks. He generally slept ok(ish) at night but past few nights/days has been waking up after only 30mins sleep and screaming when feeding! (doing both breast and bottle but he screams at both) ive been using infacol but no help! I lay him on his back fully swaddled but this isn't working now. I also tried a dummy but that doesn't help either! Is this normal for this stage? I see from other posts most babies sleep MORE at this time!! I'm starting to pull my hair out so tired and worried might be something wrong......any advice much appreciated thanks :(
