It's nice that to see the children get along together but the hospital probably wasn't the best setting for those kind of pranks. My tendency to over-think caused me a bit of anxiety when watching that. Also, why were they left alone like that in the first place? Even the eldest is still under 8. That was so irresponsible. They could have been left at home with one of the adults.
I was glad that Dhara's son was finally able to interact with other kids and have fun, rather than quietly face abuse or look after his parents.
I'd love for Raavi's son to become a bit more confident going forward and learn to enjoy with the others, but also I don't want him to pick up bad habits. He's too young and it could prove to be dangerous. Keep him as the good kid.
