Tbh I think its hard to say when you are in your 20's what you think the oldest age you would want to be childbearing. Who knows what the future holds?
I am 26 and feel like I dont want anymore now. Dh is 34 and thinks he is 'too old' to have anymore, I ask you? I dont think its that he thinks he is too old atm but I think he thinks if we are going to have anymore we should do it sooner rather than later iykwim. As we both are atm neither of us wants another baby in the works. I had just turned 22 when I gave birth to my daughter and 23 (almost 24) when I had my son. Personally for me I think it was too young. My daughter has special needs and although I dont resent her I do feel like I have missed out a bit on being young, going out etc. and not having no worries. i feel like I have had to grow up to fast and underestimated the impact having children has on our lives. I wouldnt wish them not here though and I am so glad my sister saw them both before she died. She worshipped the ground they walked on. Also my daughter starts school in september and I feel that I will be able to start doing more for 'me' instead of for everyone else. I just cant see me having anymore and I dont think its anything to do with age.
I have waffled on and on and I dont think I have made any valid points here. I think what I am trying to say is age isnt important its what feels right for you
