When there are siblings, twins or not.... never, get "one" gift that can be shared. Each child should get their own gift, even if it is the same gift but different colors. 2 year olds, also, developmentally, are not "experts" at sharing.
Just think, would you yourself want a gift, that you had to share... with someone else? Kids are kids. Get them each a gift.
At that age, kids like to play with anything...but their fine-motor and gross motor skills are still developing.
And they like to pretend play.
"Fisher Price Little People" sets are cute and fun and for this age.
If you go to Amazon, you can search for it and see the MANY sets they have. Toddlers like these. My kids did. That is what I recommend.
