Be a good listener
Make sure to have their full attention
Play games with them talk to them often how was their day or what they do today
Do vocabulary activity’s or listen to music and most importantly have fun with them and make sure to keep them clam and also you stay clam I have to watch a 10 year old everyday these are things I use often get their attention
No offense but maybe they don’t like you and are trying to make fun of you
Try acting different when they are around and see if that works just tell them your not
I would say c two years old, i’ve read stuff about that usually even younger
You start to feel not very well
I think it’s A, hope this helps
