I bought simple sleeves for my 7 months old. These are great alternative to the socks I was using to help my girl not to wound herself. Sometimes she scratch quite hard and her skin is now much better since using sleeves. I am using them day and night. But I had some stretching issues with them, so contacted scratchsleeves and they have responded right away.Very helpful, thank you Tess. I received cross-over to try and must say that I would highly recommend those for a wriggly little monkeys as my girl. No issues even when a little streched due to wearing for some time. If I need to buy again, I will buy cross-over.
