Thank you for your advice and support @llli*mimibrooklyn. I have tried a lemon...just touching it to her lips. She didn't like it. She has a sippy cup with a straw that she drinks water out of. I have tried to sneak other things in there since it a stainless steel cup and she can't see through it. She will try it but not like whatever it is. Of course then I feel bad about tricking her. I got some of those pouch things but she won't put them to her mouth and try to drink out of them. I will have to find some kind of specialist or someone for her to see to make sure something else isn't going on.
