My baby boy is 17 weeks today and yesterday me and my fiancé found his 2 bottom teeth cutting through which is amazing! He had his 16 week jabs Wednesday and ever since he's been off his feeds which is understandable for the past 2 days but he's still off his feeds. He usually takes 7oz and he's only taking 3oz per bottle so I'm feeding him every 2 hours currently. Is there anything else I can do? I don't know why he's still off his feeds and he's formula fed so I don't want to waste too much milk.
