The spaces are exactly the same size in the local Tesco here - just with a stupid push chair logo on it. Without trying to be obnoxiously rude but no one forced you to have kids - there's no reason at all why you should be entitled to a particular parking space in a car park than anyone else.
So having a kid gives you no benefits at all? Of course it does - the main criteria (I was going to link the child benefits page here but you can google it) is that the child is under 16 which is a pretty big criteria.

Lolz..
I really can't see why you think it's an 'entitlement' thing like someone is trying to slight you, the vast majority of parents don't think anything of the sort.
These are spaces designated for people that qualify for that designation, simple as..
If you don't qualify and park in them, you are an inconsiderate tool..
Sounds like you are irrationally jealous, thinking it's some status/power affirmation, which doesn't say much for yourself..
