Weaning

This website is a great resource for explaining how to prepare food for different ages and when to introduce each:

I got this from my health visitor which might be helpful

good morning, thanks for your message. It sounds as though your little one is definitely getting very ready for food! As a general rule, the current guidance remains 6m for introducing solids, though we do appreciate that there are some babies for whom milk alone isn't going to be enough until that point. Good head and neck control and some hand/eye co-ordination are definitely beneficial.
We know in babies under the age of 5m introducing food too early can increase the likelihood of sensitivities and allergies, and even if keen, they struggle with digestion before this period. You are, however, pretty much at 5m, so fine to consider trying him on some small quantities of solids from 5m. Under the age of 6m we advise just fruits and vegetables, from 6m go for it with family foods, lots of texture and flavour! Keep an eye on sugar and salt content, don't add any into his food.
