Sounds like your doing a great job the first couple months are so so so hard the sleep depravation and a little bubba trying to get their body used to this world my dd is 11 weeks and has just started to settle but still is colicky I've found infants friend helps or hylands colic tablets which are 100% natural and homeopathic
I've got dh to give dd a formula bottle (ebm if possible) in the afternoon once a week/fortnight so I can go to bed early and get a break and that hasn't effected my supply I'm a big believer in doing what you need to do to help your sanity
Also make sure the milk isn't coming out of bottle too fast that will make her throw up and yes as others say it looks like more than it is especially when your the one covered in it
