I know how you feel!!! DD is verrrrry picky too and eats the same things every week. On the rare occasion that she eats something new and different I throw a mini party over here too LOL LOL. Im glad DD liked your meatloaf!!
Congratulations!!! That is wonderful. We have a good friend with major food issues for her daughter (17 months) and the only thing she loves is my chili. She will eat it with gusto. So I sent some home with her mom and her DH found it in the fridge and ate it. The mom was so upset. Let me know if you want the recipie - I will FM it to you.
Thanks everyone, I'm still walking on a cloud-- I knew YOU GUYS would be able to feel the same joy in such a little thing!
Here's a link for the recipe, it was posted on the Food Board last week. I used ground turkey instead of chicken though. I also made the roasted broccoli recipe that's also on there (and roasted some parsnips the same way too) and it was delish too-- although she wouldn't touch either of those except for a morsel of broccoli I could cram in there before she smartened up to me!
I don't think she ate it b/c it was too good to pass up-- I think she was just feeling spunky and wanted to not age me another day with fighting her to eat Sooo proud of her!
Sooo proud of her!
