Welcome Carlie! I cant help you out with having twins as I only have 3 kids real close together but I can just imagine its going to be a crazy fun journey for you

Just wanted to say I have a City Classic double pram (not the mini) and they are fabulous! Its like a tank. You can also attach a skateboard to it if you need to have somewhere for your elder child to hop on while out and about. The weigh limit per seat is one of the highest Ive seen so it will last them well into toddlerhood. It fits through all standard doors. Well worth the $$$.
