I’m a first time mum so this all could be completely normal, but I need some advice or reassurance. DS is 3 months old. We have been so so lucky so far because he has been the most placid happy baby, sleeps well at night, and I have been enjoying every little bit of him. Until the last couple of weeks when things have completely changed. He is breast fed and is completely refusing the breast unless sleepy, and even then he might wake up and wail. We have been to the doctors and there is nothing physically wrong causing this but I’ve been giving him expressed milk in a bottle. He’s gone from 50th centile to 25th. He seems very agitated, angry, not napping well in the day, whiny, and just as we’d got him an earlier bedtime he’s now wailing until 22:30 at night. Nighttime sleep is still ok but I’m terrified that he will soon regress, I already feel quite down and stressed with his behaviour so I don’t know how I’d cope. He suffers from reflux and was prescribed infant gaviscon yesterday. I’m collecting it today so hopefully this may help. He also keeps putting his fist in his mouth, dribbling and prodding at his mouth in frustration. Could all these behaviours be caused by teething? I thought he was too young. I have tried teething gel and calpol when it seems really bad but they don’t seem to help. The health visitor is coming this afternoon to discuss the feeding issue and drop in weight. I just thought things generally got better at 3 months not worse. Will this pass?
