Baby food (purees)

I have a question ladies

Plz no bashing

My sons 8 months has 4 teeth coming in can sit on his own and is about to crawl anytime.. hes on stage 2 baby food. (Purees)

Now my sons cousin my (my bfs brother)

Is 4 months and she's giving him mac and cheese baby food , beef stew baby food etc

Cant support his head nor weight doesnt press feet on floor etc

Which baby should have it?

I just feel like she's rushing him. Noone will say anything to her cause they think its ok.

My mother in law and bf thinks its a little young being hes not really ready for it.

She feeds him out of a bottle and she puts the baby food in this feeder you would put like puffs or cheetos in its mesh.

We have the same dr and she told me not to feed my baby any of that until at least 7 months which hes 8 months almost. She said to start him off on veggies and fruits by them selves..we dont get along cause she always has something to say ab my child i just feel its a tiny bit to young i know every babys different and everyone parents different im jw if u ladies think its a little to soon

PLEASE NO BASHING
