I have this problem with a 27 month old in my care, but he is quite behind in most ways, so it is more a case of not having the skills at all...but at the same time his parents baby him, so it worsens. I am going to send out a little email to all of my parents tonight about working on these things at home as it is much harder for me to take the one-on-one time to teach how to take off shoes or put on boots etc...if they were practicing with one-on-one instruction from parents, it would go so much faster!
