toddler and thoughts of another baby

It's no secret we have an already large blended family. The Lord had blessed us with five amazing children. It has always been my dream to have a large family. The thing is, we have an enormous gap between our two youngest, almost ten years. I have been wrestling with the idea of trying to have just one more so Liv can have a sibling to grow up with. She is potty learning now. She refuses to wear diapers except to bed at night and is staying dry most nights. Her 2nd birthday is coming up very soon. Hmmm, maybe we'll start trying in a few months.
