Shared crib to single cribs

Brittany

For the moms that had their twins share a crib, I'm curious when did you start to put them in separate cribs??? My girls are almost 5months old and I feel they are starting to get cramped in there. Yet at the same time though they love being next to each other. They both move so they can be right next to each other. What was your experience and any advice you have???
