Should I force feed my 8 months old, if he hasn't taken sufficient food?

I wouldn't suggest force feeding, but yes, do try and feed ur baby by diverting attention. When my babies were fussy about food I would often sit with them on the balcony and distract them, which helped eating. U can also try letting ur baby sit in a baby chair and give finger foods. Babies often enjoy the experience and end up eating too.
