Have the babies been sexed by a vet? It's very important that if either or both of them are boys, they are removed, or you could end up with rather more rabbits than you bargined for!
They do say to give unlimited pellets to babies, until they're 6 months old. However, you want to encourage them to eat all the grass and hay that they can, to keep their teeth and tummies healthy, and if you give them too many pellets they won't be hungry enough to want to graze. Maybe you could seperate mum from the others for one of 2 short periods each day. That way, mum can have her veggies (kits are too young for these yet) and they can have their extra pellets without her wolfing them.
Now, hurry up and post piccies!
