Hello, I was 37 when I conceived and then gave birth to my son.. He hasn't asked me why I seem older, but has said, you ARE older :)
However, it never seems to bother him. Additionally, while I am older than some moms, I tend to have more energy, look younger and while a few younger moms that I know are never wanting to do much physically with their kids (they'd rather drive or take the bus) it's not uncommon for my son and I to get out and walk 5 to 7 miles in a day.. and when we do, I race/walk with him.... and will take a ride on his scooter :)
However, there have definitely been times when I felt like, wow, am I the oldest mom here...... and sometimes, I have felt out of place.. Also, I have found that many women my age have older kids and therefore, it's been a struggle at times to find a place where I fit in.. I don't always feel comfortable with the younger moms and older moms whose children are grown seem to stick with their own.. I guess you could say, my son isn't the one with the problem .. I am :) hahah but I am working on it..
despite some of the cons.... there are more pros to being an older mom.... and I wouldn't trade it for the world.. If someone does ask me why I waited... I tell em that at this age, I am a more "apparent" parent than most..... being older does bring wisdom... also, I don't sweat the small stuff like some younger moms do... (nothing against them) but it's true..
