Question about feeding 10 month old baby, Help please?

This actually sounds like a good thing to me. You'll be weaning her from a bottle/formula soon, and she's just letting you know she's ready. Self led weaning is common in fed babies, but can happen with formula fed babies too. If I were you I would just keep offering her formula as you have been. If solids aren't enough and she gets hungry she'll let you know :)
