18 weeks

[madeindevon2]

will it hurt to offer 18 week old some babyrice?

Hard to say. Why do you ask - do you want to?

it might do - you can't tell how mature her gut is at the moment, hence the advice to wait till 6 months when it will definitely be ready to digest food.

but why on earth would you want to? It's unlikely to help her sleep. If you think she's hungry offer more milk.
