My boy is 4 months and 6 days today and born a week early, maybe it’s just at thing at this age he used to have 6oz but was only having 4oz, as long as it’s half i wouldn’t worry, but if you’re worried just speak to your HV xx
After about 2 weeks he’s now back to drinking 6 again xx
My baby girl is the same at the minute, she will be 4 months tomorrow, she was 3 weeks early. Up until 2 weeks ago she was draining her bottle now she’s taking 3-4, I’ve been trying little and often throughout the day. She is still sleeping from 8pm-6pm and putting on weight so not too worried xxx
