Fussy milk drinker

[Dadliving]

My dd is 22 months and is very capable of drinking water out of various cups and beakers, however she refuses to drink milk out of anything but a bottle, given to her by myself or dw. She obviously has a strong association between being fed milk in a bottle and relaxing and sleeping as she has a bottle before bed and has done so for a long time now. When I try to give her milk in anything but a bottle she takes a sip and then refuse to drink more, usually saying her word for bottle to indicate that the drink should be in her bottle! I am diluting the milk in the bottle to put her off but this trick is not yet working.

I am stuck on ideas now for how she can be tempted to drink milk, by herself out of a cup / beaker.

Has anyone else been through this?

We've had refusal with DD when swapping from bottle to sippy cup to proper mug which is what she uses now. I'm probably a bit tough but my tactic is "it's this or no milk", if she's eating a good amount it's not a problem to not have a cup of milk for a few nights. I think the longer you leave it, the worse it gets (I learnt this with the dummy 😫).
