Re: Not enough supply for direct nursing and pumping
Welcome to the forum and congratulations on the new baby! I think the most important thing to recognize is that with a 20 day old baby, nursing is pretty much the only thing you should be doing. If you ask most of the moms on this forum what they were doing when their babies were 20 days old, they'd all say the same thing: they were sitting on the couch or lying in bed, nursing the baby all day long. Nothing builds milk supply better than frequent nursing- and that's why newborn babies nurse all the time. At 20 days, a lot of new babies are going into their first major growth spurt, which usually happens at around 3 weeks, and which can result in almost non-stop nursing until your supply is boosted to where baby needs it to be.
I know it can be really hard to go from being able to give your first child your undivided attention to needing to put your newborn first, giving your older child only the little bit of attention you have left over. But this is temporary, and eventually you'll be able to mother both kids more easily.
Do you have a sling? If you can master nursing in a sling, you'll be able to move around the house and take care of some of your older child's needs while continuing to nurse the baby.
I strongly encourage you to put the bottles and formula away. Supplementing with formula has a negative impact on your milk supply. Every time you supplement instead of nursing, your body gets the message that it doesn't need to make so much milk. And babies who get a lot of bottles from early on become lazy and reluctant breastfeeders. And 3 weeks is very early to be giving bottles. Most resources suggest delaying bottle introduction until 4-6 weeks or longer if breastfeeding is not going well.
