In the nursery where I work, we have a young child (2yr old) who does not always do what he is asked. Sometimes, when he is playing outside, he will come in for snack if you approach him, tell him it is snack time, and take him gently by the hand, and lead him indoors.
However, sometimes he does not. He is a toddler after all. Do you think it is reasonable in this circumstances for the staff member to physically lift him and carry him indoors, where all the other children have gone, for snack time? He doesn't cry if the adult does this, but does wriggle and squirm and refuse to walk, obviously not happy about being restrained. But once indoors, is happy to have snack.
Am just wondering and probably over-thinking this. He also does it at going home time, sometimes he doesn't want to stop playing and go home, and the staff have to physically lift him to get him indoors to get ready for going home, while his parent/carer is waiting at the entrance door for him.
