To not really know how to get DS to gain weight?

[NoCapes]

Does he need more carbs? Or protein? Or fats?
Bigger portion sizes? Or more snacks?
I feel like I really should know this but all of the advice I've found is so conflicting and now I don't know what to do for the best
What's the best (and healthiest) way to get him to gain weight?

Too much info missing OP. :) How old is he, what weight and height and what is current diet like usually?

What's he eating and how old is he.

Oh I was trying to keep it short and to the point
He's 6
He's 117cm & 2stone 12
He has had some eating issues in the past and we suspect some sensory issues too, so he is eating and wanting to eat more than he ever has at the moment, but he is still a tiny little thing, and underweight according to the bmi calculators

peanut butter
more protein
less snacks so he eats more of the main meal
ice cream

I found an iron supplement (ferroglobin) really helped to boost dds health and appetite (she was also underweight but a bit older at 9)

I'll give what he ate yesterday as a typical day -

B - 1/2 a piece of toast, 1/2 an apple, glass of milk

L - cheese sandwich (1 piece of bread folded over) 5 cocktail sausages, some cucumber chunks, about 8 grapes & a tube yoghurt
Cordial juice to drink

S - smoothie & a granola bar

D - 1/2 a steak, about 5 garlic new potatoes, green beans & peas
Cordial juice to drink

Milk before bed

Thanks for replies
Some major x-posting there

Well is that actually underweight? Which calculators are you using?

That sounds a great start.

I would probably ditch the cordial as it really fills them up. It was the first thing that went when I was trying to get dd to put on weight

would he eat porridge at breakfast? I used to put full fat jersey milk in dds.
And maybe some ice cream after dinner?

Adn make sure the milk is what dd calls 'blue milk' ie full fat

My Dd was like a splinter at that age i used to give her nuts yoghurt milkshakes to try and put a bit of weight on her diet was limited drove me batty some kids are just slight though

Can anyone confirm if OP's DS is actually underweight with an NHS chart? Or other trusted source? I can't seem to find one as I'm in Oz...it doesn't sound that scrawny to me...obviously not a chunk but is it actually underweight?

Yes Matt according to the nhs bmi calculator he's on the 0 percentile and is underweight

Oh I didn't know that about cordial being filling Fortune he only has a splash now but I'll try to reduce that then (he drinks water throughout the day I only allow cordial at mealtimes)
We do have the blue milk already but he's not a lover of porridge, in fact the only cereal he really likes is crunchy nut cornflakes or weetabix, he prefers more bready breakfasts - toast/pancakes/crumpets/brioche

Thankyou

Does he like milkshakes? Could you make one with a bit of full cream in there? What about avocados? I know not all kids like those but mine love them...boiled eggs?

Sneaking butter into sauces?

He is 30ish lLBs which is light for a 6yr old

I think far far more sensible to try and up his calorie intake at home before taking him to the gp for absorption issue tests

FWIW my gp noticed my dd was quite underweight at an appt for something unrelated

he did NOT suggest that there was a sinister underlying problem but to cut out squash (she was quite addicted ) and up calories as I have done and said up thread.

(and she suddenly grew taller and now although slim is very strong and wiry and eats a lot more and is extremely healthy)

tiggy he is asthmatic, could this be causing weight issues? Nobody has ever mentioned that
He's always been right on the cusp of underweight/healthy weight but he's definitely lost some wiring the last couple of months
I was trying to avoid going back to the doctors really as I don't like him to be too aware of it, it makes him quite anxious around food if he knows I'm monitoring it
Could I go without him maybe? They would want to see him wouldn't they

Within* not wiring

Sorry I'm x-posting with everyone, I'm typing 1 handed under a sleeping baby

Oh please don't take him to the gp
fwiw dd also has asthma and noone ever mentioned that
just up calories and see how is is in a few months

I secretly kept a food diary for dd as I think its easy to kid yourself over what they are eating

plenty of chicken and salmon is good as he will be growing

I would give him a full sandwich and toast id not give anything along with it or cereal i know he has eating issues and i know its difficult but half a bit of bread isnt a lot

Yes he is quite underweight, in the 1st percentile according to NHS calcs.

Oh I didn't know that about cordial being filling Fortune he only has a splash now but I'll try to reduce that then (he drinks water throughout the day I only allow cordial at mealtimes)

You don't need to bother, its nonsense that it is any more filling than water!
