Sorry, another breastfeeding past a year question from me!

C is almost 14 months, nurses 4 times a day generall. She hardly ever has bottles since I SAH and it's easier to nurse than pump and bottle feed. However she used to take pumped milk in a bottle no problem. The last couple of times I tried she just seems pretty uninterested in it- once when we were in a rush so I was giving her the bottle on the go, and once when I actually went out and the baby sitter tried giving it to her.

I know she is starting to get most of her calories through food now, and she drinks some whole milk in a straw cup- not a lot but I don't worry since she is breastfeeding still.

I'm wondering if I should be trying to give her frozen milk in a straw cup, or cows milk, before bed when she is with a babysitter, to replace her bedtime nursing, or just let it be and make sure she has a good dinner and maybe a snack close to bedtime? It's certainly easier to not have to worry about pumped milk, but I have some in the freezer so it's no big deal either way.

What works for you guys?
