Aiden was about 3months when I transferred him. To help make the transistion easier, i let him have some day naps in his cot, plus, i hung a thin blanket (actually it was one of his wraps) on the open side of his cot (solid end cot, one end against the wall) so that he wasnt overwhelmed by the sudden big view, or even a sense of spaciousness.

Like Danni, i did have something on each side of him, didnt use rolled up blankets, i just had one of those anti roll things that you buy from the shops, mine was from Big W i think, does a similar thing to using the towels.
