Don't worry about ages when it comes to starting a family...
My Dads' first child was born when he was 28, then 30 then the next one (me) at 51 and my younger brother at 56.
Only bad thing was/is that I do not know my oldest brother and sister but know my nieces and nephews like they were my siblings...
Makes for a strange family dynamic...but we are what we are.
