Problem solved!
My daughter is 11 months and she’s been refusing to hold the bottle by herself till I noticed that she didn’t had a problem holding the zippy cup so I bought another zippy cup removed the holder or whatever you call it and put it on her bottle. Problem solved! now I don’t have to hold the bottle for her. It was tiring due to my disability on my arms cause she takes her sweet time to drink 🥲😅
glad you found something that worked!
