@Caroline my girl has never been little either, she was born 9lb and has remained a chunk but at 21 weeks tomorrow she’s only 7.3kg. I’m hoping it’s just that she’s more active and nothing concerning
Aww mine is 22 weeks tomorrow and was 6.6kg last week. They're all different but she sounds a good weight so try not to worry unless it goes on for weeks x
Mine dropped from 50th to around 30th recently and the health visitor said not to worry as she had never been underweight and it might be related to more movement due to her rolling and kicking a lot (but it was actually related to reflux). Now she has a thickener in milk she is keeping more down and gone back up to around 45th centile 3 weeks later. Not sure if yours is more active recently or has reflux. She may have a growth spurt soon and feed lots more but at the moment she doesn't need lots x
