Age gap and TTC #3

I’m new to this group! I’m 30, married to my hubby for 11 years, and we have a 8 son and 9 year old daughter. We recently had a surprise pregnancy that ended in miscarriage. The idea of another baby was not something we were planning but was not preventing (since the last child). The month after the miscarriage I had a chemical pregnancy. Now we’re sure we want to continue trying but the age gap between the kids is not something I’ve ever “dealt” with. Anyone else trying for #3 with a significant age gap?
