We have a little girl who’s nearly 3 and she often complains she gets very hot. She’s always fanning herself and I’ve read a few things on temperature regulation. Is there any research on this? Is it related to the lymphatic system or could it be dealt with by diet? I’ve noticed she often gets this and she sweats a lot at night and we often feed her by tube when she’s in bed and she really sweats. I wondered whether that’s to do with fat in the diet?

I don’t know of any research but sweating at night is very common. I saw a child with Noonan Syndrome aged 10 yesterday and he sweats a lot and needs pyjamas changed. I think it’s common but we don’t know what causes it. We know that this is extremely common in children with Costello Syndrome and it tends to improve with age.
