Help settle an argument- daily puddings

[sealedwithX]

We have got into a bad habit of having something sweet after dinner every day.
We will usually have something like a biscuit, small chocolate bar, yogurt or occasionally something bigger like a cake and custard.
I have decided that it's not doing us any good. Me and dp have both gained weight and the extra sugar sometimes affects our dc behavior.

I decided today that we should stop the puddings. Maybe have them once a week but if we slip into bad habits then cut them altogether.

Dp thinks I am being mean and says that what we have is only a small amount and the children look forward to it. Admittedly, during the lockdown, it seemed to be the highlight of our day

I said he can continue to have it, it's his choice but me and the children will stop.

So,
Do you have a daily pudding?
Do you think we should stop them?

Weekdays it's yoghurt and /or fruit. I had to be strict and limit ice cream to weekends only because my kids are obsessed with it and would eat it every day otherwise.

I’ve never bought children’s yoghurt, or any food tailored to children. (Except babybels). What’s wrong with normal yoghurt?

I like a pudding with lunch and one after dinner.

We’ve never done puddings. Dh has diabetes so no sweet things get routinely bought.

When he’s in hospital the nurses always comment on his good blood sugar control, then they offer him a pudding with dinner & look confused when he refuses.
