Hi Bal,
Welcome too Mumstown.
I was like that with my son when he was little actually up until about 2 months ago when i seem to just be so broody all the time!!
i was set on NEVER having another baby, now i think hmm why not!!
i wouldnt want my J growing up on his own, i think of how much i liked having my sister around on family holidays and that and it makes it all so much easier on makin that decision that i def dnt want J to be on his own all his life.
however ur decision may be different too mine, just ensure he always has lots of friends, nothin worse that a lonely child.. 😀
