Don't burn your bridges if you are really enjoying looking after Harley and are not too exhausted!
If SIL has been the main carer and you have only just taken over then perhaps he is being over-anxious and will relax when they both see how well she is doing with you.
You do need to know what their expectations are for diet, naps etc (naps because they all need to get a decent night's sleep) but they will have to realise that you have brought up children of your own and that you are perfectly capable of looking after your DGD.
They need to relax and apply a bit of common sense to the situation.
Don't, however, let them take advantage of your good nature. You need a social life too and perhaps a couple of days at nursery would give you a break.
Good luck!
