Our eldest daughter developed baby trich just after turning two years old. We would find balls of hair in her hand and almost always discover a ball or two in her bed in the morning, after a night's sleep. We believe the trich was a settling mechanism for her, as she did not have a favourite soft toy or comforter. She would suck her fingers on one hand, while the other hand would play with her hair. We tried a number of things to try and encourage her to stop, but the difficult time to deal with was nighttime, when she would pull her hair whilst half asleep. It was a stressful and upsetting period as parents. However, we discovered scratchsleeves and introduced them at sleep time. The physical barrier that the sleeves provided solved the problem at night and nap time. I don't know where we would be without them. We could not recommend them highly enough. Our second daughter also started showing a tendency for playing and pulling her hair, at around one and half years old. We were able to introduce scratchsleeves straight away. Both children now seem to have lost their tendency to go for their hair. However, now five and three years old, up until just recently, the girls have still been wearing their sleeves at night, as it was part of their routine and they were happy to do so. However, just last week, we stopped using them and so far so good. Thank you for a wonderful product.
