I must say I feel the same way.
I have been blessed with three beautiful children and three wonderful pregnancies and births.
I had always said I wanted 4, DH has said 3.
So we have three. I would love another little bubba to join our clan. In reality I don't see it happening unless its a whoopsie.
Dh likes the comforts of life and with our eldest being nearly 12 I think he is looking forward to some grown up times, although with the youngest being 2 its a long way off.
