DS is 4 months old and is BF. I stay at home with him and nurse the bulk of the time but he's gotten a bottle of pumped milk a few times a week (since he was 3 weeks old).

Last week he started refusing the bottle. I thought maybe the (thawed out) milk was bad, so I tried giving him freshly pumped milk and he still refused it, and has since. I know he's hungry because he's giving me hunger cues, and when I give in and breastfeed he goes to it like he's starving.

We've tried different bottles, and different people (DH, MIL and FIL have all tried) to no avail.

Is this normal phase?
