When did you seperate your twins?

lisa • Mom of 1 girl👧, 3 boys👦🧒🧒, twin 👧🧒( born 2/4/20) and one in heaven 👼 #nosanityleft

My twins are 4 months old still in same crib. I can put one on each end yet somehow my lil girl ends up snuggled next to her brother every night. Last night she started fussing i get him to check on her when i see my son put his head on her and looks like he kisses her head. She falls right back to sleep. It was so adorable, but im not sure how i am going to seperate them if they snuggle for comfort... what did you guys do? ( also yes he is using a flowered wrap he spit up on his so he borrowed his sisters lol)
