Basically this is the story - baby 4 months old, takes 5 bottles a day, sleeps from 8pm till 6am. He takes 6oz every 3 hours during the day but it's a constant battle to keep him going for 3 hours, after 2,5 he would start fussing. I tried 7 oz, he would finish those but again after 3 hours he would start fussing. My pediatrician (yes we are under ped at the mo) said at this age babies should go 4 hours between feeds, then I can increase to 7-8 oz. And said he defo isn't ready for real food yet coz he needs his milk bla blah. What should I do? Keep him on 5 x 6oz bottles a day which works out every 3 hours (30 oz a day) or try and switch to 4 bottles at 7-8 oz? What do they do at this age?
