We had our kids after 7 years of marriage and loved it at kinder & school as they didn't realise that I was about 5 years older than them. Great way to stay feeling young.
By the time they get to late primary/secondary things even out.
You will find a new friends as your children find friends when they start kinder/school.
Make the most of this time as you will become a grandparent before you realise it, time goes so fast.
