Re: Green poos!
Welcome to the forum, and congratulations on making it through the first 5 weeks of nursing! Please don't beat yourself up about not having the confidence to nurse in public. A lot of moms don't, at just 5 weeks- especially first time moms.
First of all, in an otherwise healthy and growing baby, green poo is NOTHING TO WORRY ABOUT. It can be considered a normal variation. You only worry about it when the baby isn't growing or developing normally, or when the baby has a lot of allergy symptoms. And in those cases, you would be concerned only when the poo is green all or most of the time, blood-tinged, and/or filled with mucous. In your baby's cue, the green poop is probably a result of lactose overload from you going too long between nursing/pumping sessions, when you were overfull when you returned home from the wedding and again the morning after the baby slept a very long stretch.
Second, empty breasts are pretty much a non-issue. When mom's supply and baby's demand are well-matched, you can expect to rarely if ever feel full or engorged. Feeling full/engorged means that you are making too much milk, or have gone too long without nursing/pumping.
So, what should you do at this point? Here are my suggestions:
1. Let the baby nurse as much as he wants, even if that means spending all day at it. This is the absolute best way to make sure that supply and demand are matched.
2. Watch the baby's diaper output. Ignore the poop color and watch for number of wet/poopy diapers in a 24 hour period. If the baby has sufficient wet/poopy output, he is getting enough to eat and there is absolutely no need to supplement with formula.
3. Offer both breasts at every feeding. When a mom is concerned about supply, she does not want to tinker with her foremilk/hindmilk ratios or do single-sided feedings, because both of those things will lower supply. Foremilk/hindmilk imbalance is a problem of too much milk or going too long between feedings. It is not a "not enough milk" problem.
4. Think about your goals with the bottle. Do you want or need to incorporate bottle feeding into your life, or are you only doing it because you think you should? When a mom hits a rough patch in her nursing journey, it is almost always best to put the bottles aside until nursing is going smoothly.
5. Your 6 week postpartum appointment is right around the corner, and at it your midwife or obstetrician will likely ask you what form of birth control you want. Since you are currently going through a minor rough patch, I think it makes very good sense for you to avoid all hormonal contraceptives (pill, minipill, patch, ring, Mirena IUD, injectables) for the time being. Even the supposedly "safe for breastfeeding" contraceptives can impact supply in some moms, and I think it makes sense to make sure that breastfeeding is going really well before you start taking risks with supply.
