Not wanting much milk

[Fullmoonfarmal]

Hello! We have been raising our squirrel since 5 weeks. He is 10 weeks now. He gets mazuri blocks plus 2-3 Henry's blocks per day. He also gets veggies and the occasional grape. He actually refuses the Fox Valley milk sometimes and only eats 6 or 8 ml of milk which is offered 3x per day. Hes behaving normally otherwise. Im just worried he's not getting enough milk! TY

How much does he weigh?

I do not have a way to weigh him. He looks fit and is very energetic. He is not fat, but does not look skinny either.
