Please help baby weaning


My babies 6 months old and I've just started giving him porridge for his breakfast with 6oz of milk. And then 4 more bottles of 7oz formula during the day. but I don't know how to go from there. I'm not a new mum but weaning had changed since my last child (who you could weaning at 4 months,give juice and water). Do I go a puree at lunch and give him sips of water after next ? Can I give him a small bottle milk say a couple of hours later if he needs it ? What about finger foods? I have so many questions it's so confusing. Sorry if I seem thick but I'm really stuck. Any helps appreciated.
