I suppose a natural instinct took over fraggle. I felt just like you once. I didn't want kids at all and neither did my OH. We had a good life, travelled, renovated a house and did as we pleased and life was great. At about 33/34 we just decided that it would be nice to have a family and to share our life with a child and I have to admit it changed our lives and probably changed it for the better. We still went on doing the same things but the child brought an entirely new dimension to our life which was absolutely great. I never felt the need for any more or got broody about babies.
Our child was thought about, planned and wanted. The time was right.
I have never felt particularly maternal, but that child (now adult) is the best thing that happened to us. And now we are older and he is an adult he still brings us a lot of joy.
I don't know how old you are, but you may or may not change your mind. Life evolves and we change.
At the end of the day though it is your choice and nothing to do with anybody else.
I agree with New Judge early in the thread. Having a child is a total commitment and shouldn't be taken lightly. I knew if I had a child that child would be my first priority for a long, long time.
