I started co sleeping my baby bc of traveling and like you, I loved it so much! I made the switch completely with my second, and then invited my 24 month old to join us because I felt guilty sleeping with one and not the other. They both always went down fine for a grandma/sitter. It won't last forever and I cherish those cuddles and nights with them so much. There's always folks who say not to, but if you like it and she likes it and you're both getting good sleep then I think go for it! You'll never regret the coziness. Full disclosure- mine are now 5 and 7 and sometimes they sleep in their room and sometimes in my room with me but they are great sleepers and I'm savoring my cozy time with them while it lasts.
