I had my baby weighed on monday. He has gone from 90th% at 4 weeks to 30th% at 17 weeks. His weight started to go down after bottlefeeding for a week while on antibiotics, since then I have had thrush, bleeding nipples and mastitis. The HV said that because he hasnt been unwell I must have him reweighed before christmas and they will discuss weaning him. I wanted to wait until 6 months and I dont think he is ready yet. DS also has reflux and is quite a wriggley baby I thought these things may contribute to him not gaining weight? Would weaning even help with weight gain? Has anyone else had this problem?Any suggestions appreciated
