Getting calories into toddler

[Namechangeymcnamechange11]

DS is 16 months and dropped down 2 centiles. He started nursery and is almost permanently ill. The first thing to go when he's poorly or coming down with something is his appetite.
I need to build him back up as he doesn't have much weight to him.
We generally eat healthily and are veggie so various stews/lentil dishes etc. He loves pasta so trying to give him plenty of that when he's well.
So far:
Plenty of yoghurt/milk
Putting cheese in omlettes

Any ideas please?

Raisins, dried apricots and other dried fruit. Smoothies.

My DD was like this when she started nursery. She eventually started to put weight back on and I'm not sure there's much more you can be doing. Just one point, toddlers can often be deficient in iron and being veggie will make this more of a risk, so I'd make sure that he had a multi-vit with iron.

My son has multiple food allergies - one of them being cows milk so we really struggle to get fats into him. He’s tiny for age - still in 12-18 month clothes at 2 and a half.
I offer him:

• fruit smoothies with (dairy free) yoghurt and his alternative milk.
• Hummus (which is practically just a pot of fat!) with crudités and breadsticks
• Avocados (tons of “good fats” apparently). I offer them in their whole form, blended into smoothies and pasta sauces etc
• Add olive oil (or whatever oils you use!) to as many recipes as you can.
• Any recipes that call for coconut milk (curries etc), I use coconut cream instead as it has a higher fat content.

After I was ill I had no appetite and needed to gain weight. Cheese Omelettes and Complan milkshake drinks helped me.

Not sure if Complan is ok for very young children though.

Lots of ideas on this old thread

That's brilliant @intovalhalla, he's not a sweet toothed one and I struggle to get fruit in him. Hummus and avocado seems a brilliant option. I tried him with hummus a while ago but he didn't like it, but I make mine very garlicky so I shall make a toned down version.

Peanut butter
Cream in everything

When I was younger and very thin I was struggling to conceive. The GP told me to add a slice of white bread and butter to every meal. That’s automatically 500 extra calories a day without any effort. I put on half a stone in a month

They can't have complain but can have nesquik! Which is high calorie, tasty, and has loads of added vitamins including iron.

Nut butters! Toast with smooth peanut butter and a bit of jam. Or apple slices dipped in or spread with nut butter.
