Regarding getting a child to eat veggies...it doesn't necessarily get harder. Up until he was 2, my youngest wouldn't touch veggies. So, I kinda gave up and would just offer him a lot of fresh fruit instead - occasionally, still putting veggies on his plate hoping he'd try it. Well, one day he ate the veggies and then just kept eating them after that. Now I put fruit and veggies on his plate - and he goes for the veggies.
So don't give up hope. I'd just keep offerring the veggies and not worry too much if he prefers what grandma gives him.
This was my experience too. My toddler is an incredibly picky eater so he only eats mac and cheese (with tofu), crackers, and some fruits. Its a struggle to get him to eat that. So if you have him eating veggies, OP, then you are way ahead of me! Relax, it won't cause him to be obese.
