Solid food preparation

Hi mummies how should i prepare food for my baby? Is it a must by 6 months i have to make mix porridge with meat and vege? Do i have to cook it and then blend then strain it only then can serve to baby? I have bought philips avent food processor i was just thinking if i can dump the ingredients and steam then blend it, like that do i still need to strain? #firsttimemom As i am working and have to prepare food for baby (my cousin take care but she wants me to prepare all the food for baby) so just thinking what is the easiest way and more practical?
