After reading my blog, my friend Adair reminded me that you shouldn't thaw out breast milk and refreeze it even to use in baby food.
So we are throwing all that food away. I did feed her some bananas that were pureed with old breast milk and she has had some really bad bowel movements the past few days. So i skipped a day and have not introduced any other foods yet.
Thank you Adair for letting me know!!
I am going to the market now to buy fresh veggies and I'll steam and puree the food all over again with fresh breast milk.
