I have three young children and i love them to bits i see the enjoyment they get from spending time with my dad (their grandad) and hope one day they do make me a granny and i can experience that too (tho they still very young atm) but if they decide not to have children then i wont be bitterly dissapointed, i found out by doing it just how hard it can be how dedicated and responsible you need to be and its the most stressfull and scary thing ever. (been the most rewarding too) i would never judge anyone for not wanting to have children after all its their life. if my kids are happy i'm happy!
