anyone else is curious I decided to answer questions in a post. Some asked the boy's ages and they are: C- 38 months(3 in November) D-26 months (2 in November) and Jack is 10 months.
The other question is about how to teach a child to use scissors. This is how I do it but that doesn't mean it's the right way;)
In the beginning I let them try it however they want and then when they start to struggle and say it's not working I ask if they would like to see the way I hold them. I then demonstrate with my own pair of scissors. I never put my hand over his or anything because at our preschool we let them self correct and all of them eventually got it. Also, I never force the boys to learn anything, if they aren't interested in cutting then why have them cut? Instead find some activities that strengthen the muscles they will need when the start cutting (ex. transferring with tongs or tweezers, using play dough scissors with snakes of play dough, those little castanet musical instruments). Make it fun.
