Abortion

I have been married for more than six years now and have two kids of age 4 years and 3 years. Handling 2 kids has become very tedious for us as we don't have anyone to support us (as we live in the city for my job and parents are back in town) and both the kids don't eat well and are quite trouble makers. So we had many sleepless nights and late mornings. Managing them has become so tough that we are losing cool on small things and getting into fight frequently. Yesterday we came to know that my wife is pregnant again and we are in confusion on how to re-act to this. My wife thinks that it is best to avoid it now considering the current situation and plan it later on for the third child. She thinks by using tablets we can do this. I am not sure how to react to this!
