My dd has done this to me as well! She used to eat oatmeal at least twice a week, and she has some issues with needing iron, so I love that she loves this oatmeal! I add a bit of cinnamon and she has loved it since she was an infant. But a couple of months ago she was like "I don't like that anymore."
So I didn't make it, and it bummed me out! The other day, I didn't ask, I just made it...and I said "Brekkie is ready" and when she saw it she was like "But Mommy, I don't like that anymore!" and I acted sorry "Oops! I guess I forgot! But anyway, it's super delish, and I put in extra cinnamon...maybe just give it a try, if you really don't likt it, I'll make you some waffles." and she sat and happily ate the entire bowl....so go figure.
My point is, don't take his word for it LOL.
ITA with "I don't like" can just mean "That isn't what I had in mind".
