We're doing one veg per day for 2 weeks then we'll mix it up a bit. I have heard not to start with too much fruit as they're sweet and then they won't want the veggies but honestly do what's right for you and baby, I don't think you can really go wrong as long as you're being healthy (no sugar or salt) so I don't see the issue with giving them what you have in house already
I suggest you get a good book about weaning which explains everything so that you feel confident. I read ‘how to wean your baby’ by Charlotte stirling-reed
When we start, we will be doing 1 thing for a few days. So broccoli for a couple days, carrots for a couple days and so on. They recommend trying one thing a few times before moving onto the next. Weaning charts can be good to guide too 🙂
