I have twins and I haven't bothered. They haven't seemed to naturally wean at all so I think they are happy. Not signs of it being detrimental to them so we'll carry on.
Ours has her milk before bed in a straw cup because she’s on the milk ladder I have to keep offering if to her to keep her calcium up but no bottles since she was 2 and apparently that was too late but I had no idea 😂 was not an instant transition but made it the new routine
We are at this point too… we need to just do it but neither my husband or I have got the energy for the fight at the moment. Waiting until we feel strong and then we’ll just explain in the day bottles are going to the bin and from now on he has his own special cup for milk- I still need to buy one. Sending you strength because I know that it could be tough if your child is as strong willed as mine 🫣
