Mine are 9 and 7 now.
My parents collect them from school but wraparound care still costs up to 450 a month. I'm fortunate that I work term time only so no holiday care.
My youngest still gets universal free school meals but it's 2.50 a day for school dinners so that can be 50/ month which will double once my younger one moves into year three in Sept.
Swimming lessons cost 7.50 each a week so approx 60/ month for two.
Football club subs are something like 15 each a month.
School uniform prob about 300 for two children every August. They're on their third pair of school shoes since Sept now at30/ each a pair. At present they change shoe size about twice a year so trainers etc.
Mine are the same gender so only the oldest usually gets new clothes which saves some.
A birthday party for only ten children costs 170+
I live in a bigger house, use more electric, gas and water than I would if I didn't have kids. I use my car more to take them to clubs etc than I would if I didn't have kids so there's petrol.
I pay for life insurance to pay out to them if I die which I wouldn't do if I didn't have kids.
I save 65 each a month for each of them.
Then there's the entertaining them in half terms etc.
I had mine very close together so still needed the cot for my first when second came along so some of the baby bits I had to buy twice and I ended up having to buy a double pram so a slightly larger age gap I think night save a bit of money if you wanted two.
