Re: Won't open mouth to eat
That's what I'd do, just try again in a few weeks. No rush!
Solids are just for trying out right now, no need to feed a ton of meals unless you are planning on weaning soon (which at 6 months you wouldn't be). She's probably not very hungry, breastmilk is all she needs!
Also my LO would NOT take food from someone feeding it to him. Mainly because he had a problem with mushy food, so he liked to feed himself. There's a ton about Baby led solids on here, you might give that a whirl.
