A bit of background.....Ds2 is ( just 5) is small for his age, but is not a skinny rib - unlike his older brother. He has noonans syndrome, which can lead to smaller stature. Anyhow.. recently I have noticed his trousers are falling down , a lot , so he has obviously lost weight. he hasnt grown in height, and I havn't noticed him eating less. He has just started school, but has school dinners as he did in his nursery ( it was attached to the school, so he ate the same dinners) .
So, my question is, should I worry about his weight loss, or just keep an eye on it. He has a minor heart condition, so I am always a bit more aware with his health, but dont know what the rational response is to this.
Thank you
