Hey mama,
Now is okay to start! It’ll also be good to do food purées like avacado, sweet potato, apples, carrots and so on! Mix it up so that baby gets introduced to a good variety instead of just cereal or porridge everyday.
You can refer to this article regarding introducing baby to solids:

Alternatively you could look into baby-led weaning which many mums find useful:

Hope you find these useful!
