I wasn't allowed in the same room as my elder brother's train set, and was told off in no uncertain terms for daring to touch my other brother's Dinky cars and the brilliant system of tunnels and tracks he'd made for them in the sand heap. He got two live pigs (and the profits from them) and a mechano set, while I was supposed to play with DOLLS
. I never understood what I was supposed to do with dolls

When my first son was born, I got a mechano set - not for him but for me
I love everyone's ideas, but I think it's worthwhile discussing a few things with the mum to be so you have some idea about her approach to having twins. Basically will she be maintaining their individuality, or does she want them to match. You might get some clues by how she treats the older child.
I love the idea of the cot blanket as a farm yard, or a zoo, or a magic forest or similar. But you'll need to make two different ones, and I agree something for the older sibling.
Sounds like you need to get working MGM
