Rolling and Tumbling

My 2yrs old son still have yet to adapt to CC since August this yr. As my husband and I have to leave for work at 6am and work shifts, most times, my 55yrs old mother, with frequent complain of knee pai would assist in sending him to CC nearby. Today was a bad one for my mother. She called to say my son was rolling on the floor near his school refusing to enter. Being carried and he was strong enough to breakfree. CC teacher did not assist or step out of CC to welcome him. What can i do? Carry on to force him to go CC? Or he dont like to be in that CC?
