Also, please offer Fela his new jeans trousers to wear any day. There is no need to save them for church. He should have 4 pairs. He can wear them with or without his belts. He has two new stretch belts which should be long enough.
Fela has worn trousers and belts before so he knows how to fasten belts.
Just check periodically to ensure his belt is not too tight.
Thank you for your co-operation!
