I'll be 35 and my DH 37 this fall. My hubby's worried about his age, since we think we want 3 and he doesn't want to be 'ancient' when the kids graduate university. Mostly he's worried about his energy level and being able to keep up with them, playing sports etc.
We're already finding with our son that he brings so much energy into exploring and playing we get revitalized just being around it. Its hard not to get swept up in all the excitement with a giggling smiley boy
To be honest, I just wasn't ready to stop and have my freedom done with when I was 26, 27...even 30. I was in school, did my masters and worked...then I wanted to travel (since I finally had some $ to do it). It wasn't till I was 32 or so that I finally felt ready to press pause to that part of my life and redirect my focus to baby and building our family. I am so glad we waited and feel we are much more patient and ready for the challenges because we took our "me time".
