DD can JUST read to herself and is at the stage of reading picture books to herself (including new ones if they are simple), what are your DCs into that are similar? She likes Meg and Mog, and Mog the cat, and we just read Dinosaurs love Underpants but when I suggested I get her a few more of those for her upcoming birthday she said BUT IT HAS TO BE A SURPRISE MUMMY.
So not those.
Bonus points for readable by me. She has several that are completely tedious.
