Is baking for the kids making me fat?

I don't actually like baked goods that much. But I find it's one of those things that the more you have the more you want. I used to nanny for a family who LOVED home made baked goods. About 3 times a week I would be whipping out the shortbread recipe, icing a chocolate slice or rolling out a ridiculously fattening cookie dough. Now I nanny for a very healthy family, who only have very good quality healthy food in the house and NO sweets. When I first started a few months ago I would get actual sugar withdrawals at about 2pm leaving me with a pounding headache and the shakes. So now I have found a compromise. I bake, but only (semi) healthy treats - everyone is happy and hopefully I will lose some ass weight now. Please?
