When did you take the bottle away?
My oldest weaned herself at 9 months old.
My middle weaned herself at 10 months old.
My youngest weaned herself at 8 months old.
I also started them with sippy cups at 3 months old.
About a year. I started her around 7 months and for the most part she took the sippy pretty easily.
11mo with 1dd and starting to now with 2dd at almost 10mo
My DD is 11 months and we still give her 1 bottle before bed. She could care less about the bottle though, she was breastfed until just about 10 months so she's not really hooked on the bottle. I'm just going to stop giving it to her at 1 year, she prefers her sippy anyway.
My daughter would drink water from this starting at 7 months so just a little bit before 10 months I offered formula in it and she was perfectly fine with it so I took the bottle away. Now she is 11 1/2 months and drinks from other sippys too.. She isn't picky about it.
