All you breast feeders out there,

I need my fears assuaged.(bet ya didn't know I could talk so high falutin') As you know my latest g'son was born Nov 19. Momma is breastfeeding(something I didn't do). Jacob sems to throw up alot, gets the hic-cups alot and is very gassy but not like cholic.(yet) I'm wondering if this is normal. My concerns come from the fact that Karen was like this as a baby, could not take regular or soy formula. Momma says she is eating right to the best of her knowledge. This is one very wide awake little guy. At 2 weeks, she will bathe him and feed him and he will stay awake for the next 3 hours. WOW!! Am I worrying too much? Is there something she should be doing that we don't know about?
