I know what it is like my DS isn't on the chart for weight anymore and i worry with every illness as it affects his eating. I can't get anymore into him either. My DS is about on the 75th for height and head about 25thish...I've stopped looking at the graphs as they stress me too much. His weight was on the 75th when he was born and slowly dropped off the chart over the year. We have a paediatrican and have gone through a couple of rounds of testing poo/wee/bloods and nothing has been picked up to date. We had a referral to a dietician but that hasn't led to a weight increase. His weight is compounded by not being able to eat dairy.

Due to months of consecutive illnesses (started childcare) and little eating we ended up seeing the GP for weekly weigh ins until he gained more weight.

All up, the doctors are cautious but not alarmed because of the consecutive illness, our families are thin, he is reaching developmental milestones, he has some fat around his thighs, his height is following a curve (it would be more alarming if this was dropping too so they tell me) and tests have come back negative.

One thing the doctors told me is that when they get illnesses and go off their food they eventually go through a really hungry patch. After many weeks of illnesses we finally got a break over Easter and sure enough my DS was just eating all the time.

I know it's hard not to worry particularly when you see their appetite drop off. Do what you can but also accept that somethings are out of your control. I reckon a good and supportive GP is a key to both monitoring your bub and also supporting you. A paediatrician is good for overall monitoring and a specialist look into and ruling out any more serious things, but a GP or maybe a nurse even is important for regular support
