Ok, Olivia was 11 months old. She was still tiny and still sleeping well in the hammock, but for some reason we decided to transition her. She moved to a cot no problem at all.
Charlie was bigger and wrigglier, so he was moved into his cot at 9 months. He was probably the "hardest" to transition" but looking back he was a little sick at the time too (ear infection) but it still was only a day or two of him getting used to it.
Lexie, she was a week short of 12 months......just last week! She transitioned no problems at all.read aboout it on my blog:
