How to make little one sit properly and eat during meal time,

My boy is 20months. Still sit on high chair during his meal. Only after meal then will put him down. I usually will on TV my channel that I wan to watch. He will watch. Sometimes he find it boring. Make some noise. I will bring ipad and play his favourite show elmo. Musical show with song. Or somethings I will bring his car toy and let him play while eating. So far so good. Maybe u can try. What your daughter likes and want. Or you can sit and eat together. I also will eat and on the dinning together with my son. So when he sees me sit and eat he follows.

I face the same issue and would like to know too!
