Dethawing milk - how to know when its bad?

[Sarah-B]

So I have milk from October I just dethawed & it tastes a bit sour but not awful is it bad?

I mean I think since I don't like it I shouldn't give it to my 9 month old but I don't want to waste it.

Also 2 days ago I pumped & put it in the fridge & this morning I pumped & did the same & the milk from 2 days ago tastes a little sour and the milk from this morning tastes great.

Should I use my October milk, my milk from 2 days ago?

Or should I dump it?
Thanks

Also want to say that our fridge is really cold & so is our freezer
