my almost two year old boy is been really active and can't stay still. my 3 year old girl behaves good but a lot of times both of them together are so hyper. I'm gonna end up in a mental hospital with this 2 and a newborn. lol God help me. Good thing my husband is taking at least the first two weeks off to help me.
