I wouldnt worry to much unless she dramatically loses wieght , my daughter was always a little thing from age of 1 and upwards would be in 9 month clothes, but she soon grew and has a little belly now and fits into the right size she should be.
Babies grow at different stages when it comes to wieght , she will get there!
HV always has something to say wether wieght is slightly over or under, i NEVER listen to them , you know your daughter and what she needs, if she isnt taking more solids then she doesnt want them just yet, she is still young so chuck her on the boob when she wants, afterall that where all the goodness is
