This thread is like playing bingo for bad weaning information. It’s amazing how the same tropes come up over and over.
Myth 1: ‘Baby rice is useless’. It’s fortified with nutrients and baby cereals can be a fantastic source of iron in weaning babies (formula fed babies don’t really need much iron but bf babies do. Low iron levels in infancy have been linked to lower test scores in school children, so iron is incredibly important).
Myth 2: ‘You should wait til six months’. The WHO gives a blanket recommendation of six months in order to preserve bf in developing countries. In fact, when you look at recent allergy studies and the resulting protocols, babies at risk are fed quite large quantities of allergenic foods starting at a very young age. Weaning late is linked to food allergies - for example, a recent study found a link between bf and food allergies, probably because bf mothers are more likely to delay weaning.
BLW is just a daft name for something you’d probably do to some extent anyway without having read about it. It just means you give your baby intact food as opposed to purées and let them play about with it a bit. Not much goes in, so you have to be careful (again) that they’re getting enough iron etc.
If I were to wean again I’d start around five months and wean onto allergenic foods (my 4yo son has food allergies), including nut butter purées and cooked (not baked) egg. I’d do a mixture of purées and intact food as I saw fit. Also, I’d buy the purées because it’s worth it not to have to make them and have a freezer full of tiny cubes of frozen carrot.
