I had a few bottles of BM in the fridge from early last week. I went to put it in the freezer last night and the fat that lined the bottles dropped in the milk and it was chunky (the fatty milk, not the regular milk). They could possibly bee 5 days old, but I had never seen that. I put them in the freezer but wondering if I should feed it to her. It smelled fine.
Yep, my milk always get chunky after a couple of days of separation, but it always mixes back in when warmed and it's never smelled off or caused any trouble.
