DS is losing weight, high fat food suggestions please

[IGIG]

My 6.5yr old is not gaining / not maintain/ losing weight. I've seen the doc and he says to give him high fat food. DS is a snacker and a ok ish eater but last 6m he has not gained any weight and stick thin. How do I get him to have a healthy weight gain?

My DS2 (9) is very thin, he lost 6kg since August and has only put 0.5kg back on due to medication that he needs to take. He has very little appetite, so we have to try and get as much in him as possible.

Currently, under dieticians advice, I am giving him plenty of nuts, nut butters, seeds, butter on and in everything I can (even in baked beans), a concoction that we call "DS's Mighty Milk" which is 3/4 full cream milk with 1/4 double cream stirred in. I use this for porridge, milkshakes, smoothies etc. I also give him the luxury adult yoghurts, rather than the kids ones as the luxury ones tend to have cream in them. Also custards and making jelly with milk.

I also supplement his diet with Pediasure drinks, its a tin of powder a bit like baby formula but for older children. We get it on prescription but boots and Asda sell it over the counter.

Does he drink milkshakes?

I am having the same issue with Ds, attempts to get weight back on are failing and he is now 1kg down from last October so waiting on dietician appointment

Ok, if that's the case then try him with the suggestions on here and keep an eye on his weight/height. But you know him best, if you're not happy with his weight before the 6 months is up then get him back to the GP, squeaky wheel and all that.

You'd think being told to put weight on would be fun/easy but the reality isn't! Good luck, please try not to stress, for your own good but also your DS will pick up on it as well

Thank you all, I'll try the ideas.

Oh and things like pastry are really high fat - DS2s DofE leader told them that pork pies were an excellent food for expeditions... DH and I just looked like since a pork pie would sit in your stomach like a brick and is not the type of food you'd want on that type of activity. Try giving him a Yorkshire pudding on the side of his meal etc, just to add calories without bulk.

IGIG, I think you are right to be wary of filling your son up with chocolate etc. DS2 was hugely underweight and underage when he was younger and we got so desperate to get him to eat anything at all, we got into very bad habits of allowing lots of highly processed foods. Of course he acquired a taste for them and is now slightly chubby. Looking back, I wish I'd allowed a more gradual weight gain. Easy to think in retrospect though. At the time he was a skeleton.

Good stuff that he liked:
avocado pureed and mixed with full fat Greek yoghurt
humous mixed with full fat greek yoghurt (both dips on french bread or flatbreads)
peanut butter, jam and cream cheese sandwiches on wholemeal bread. (We used to use cream cheese instead of butter as you could spread it more thickly and it had higher protein.)
Home made cake, made with 50% ground almonds in place of flour, and with loads of eggs and butter in. You can make chocolate cake, brownies, vanilla sponge, almond cake from this recipe.
cheese sandwiches, cheese toasties, homemade pizza with added cheese.

Like your DC, he ate tiny amounts, so we needed to make sure that if he only had two or three bites during a meal, they really counted.

Banana milkshake made with milk, single cream, banana and a scoop of vanilla ice cream.

Also, our dietician told us to make sure he had five meals a day not three. Unfortunately the habit has stuck. It was: breakfast, lunch, after school snack, dinner, supper. On weekends, also to add elevenses. I used to do things like a cube of cheese, a cream cracker and half a pear or apple for the snack meals with a glass of milk or a smoothie, so that if he didn't eat later, at least it had been reasonably nutritious.

Any teeth issues that might make eating painful. We have that now and again.

Going from experience with My 2 boys they both went stick thin around this age despite eating well. They both grew taller around this age too making them look even thinner. I never weigh my dc couldn't tell you what centile they're on.
Cheesy mash with butter and maybe cream instead of milk is quite calorific and a big hit in our house.
Ds1 eats constantly both healthy and unhealthy foods (probably more biscuits than I'd like) he's been skin and bone for years he's very sporty so I think he burns it all off easily.
Will your ds drink milkshakes??? Tesco do small cartons of strawberry and chocolates milkshakes that my ds2 absolutely loves.
