My daughter eats all the solids I give her. Do I keep giving her more until she stops eating?

I've been weaning my daughter for about 3 weeks. She is almost 6 months old. She is in the 91st percentile despite being exclusively breastfed (apart from the solids, now) and eats everything I give her. In the last couple of days I've brought in an evening 'meal' (previously I just did breakfast and lunchtime solids) and she eats that too. I'm still on 7 milk feeds per day and she has been waking up in the night lately whereas she slept through the night from about 7 1/2 weeks until she was about 4 1/2 months old. I have been defrosting 2 or 3 'cubes' of food from my icecube trays for her. Should I defrost more and see when she stops eating? I seem to remember a Health Visitor saying that a couple of years ago with my son but it didn't really apply to him because he wasn't as hungry as my wee girl seems to be! I don't want to upset her wee tummy. Many thanks for any advice you can give.
