Hi rosettastone - I had my babies in my early twenties and loved ever minute of being a Mum when I was young healthy and had plenty of energy. But now that I am a lot older I sometimes wish that OH and I had had a bit more fun together a few more carefree years. But the other advatage of being a young Mum is that we became grandparents while we were still young enough to enjoy young children and to do things with them. So I suppose my answer would be that there probably isn't and ideal time just enjoy it when it happens.
