Mines 17kg sometimes he survives on fresh air and others I can’t feed him enough, he’s really gone off his food lately though 😔
My 3 year old boy is 15.9kg. He’s non shop running about, doesn’t eat a lot either. I think this is an ok weight (I googled it as I was concerned because his waist is still so small) he just looks tall and skinny 🤣 x
My girls around 13, she's not skinny but she is petite and slim. However Im also petite, very slim when i was young..I have tiny feet and hands etc. My 1 year old is 9kg but he's built like a rugby player like his dad. I think as long as they look healthy your fine, everyone's different. If you can see ribs etc I'd call the gp and they can do checks.x
My boy is 13-14.
It doesn't sound like you're doing anything wrong. My oldest was 13.2 at 3.5. He's just slim. Some kids are. If you're really concerned, perhaps speak to your health visitor? He's 5 now, he eats like an absolute pig, he out eats me every day, and is still slim. His younger brother 3.5 only weighs 1kg less than him but doesn't eat much at all compared to my oldest.
Mines only 15/16 and does nothing but eat. He's just tall and skinny
