If anyone tells you that it gets easier as they get older, it's a lie
My three are 11, 9 & 9.
I used to have a copilot wee ride on the front and another seat on the rack for taking two out at a time. The copilot means you have to ride with your knees right out so that wasn't very comfortable
Yep, twins. First one will be about 16 months when they arrive so 3 under 2 is going to be an experience
