Trying for another?

Kaity
So my husband and I have three beautiful kids. Babies really. A 3 year old, a 19 month old, and a 4 month old. We will have 4 months before we are even going to talk about number 4. But I'm afraid to talk to anyone about even thinking about having another. Any time we are around friends and some poor soul asks if we are planning on having another, all my friends start yelling "no. They need to stop having kids! She's spent most of her adult life pregnant!"..... But these are the same people that feel strongly about "my body, my choice". Anyone deal with this before? Any advice?
