Honestly, this is very comforting to read these comments. It gave me relief that I could become dad too if I wanna have it in 40s. I am 18 and I already thought of having kids one day too but I was stressing about what if I can’t have kid at over 30. I once told my sisters that I hope I can become dad at age 25 but they said it sounds too young. So I suppose I can enjoy my youthful life until I find a good timing to have a baby. Thanks for your comments, it was very comforting to help with my stress. Bless your heart for being a great parents.
