Quoting Lotus Mama:" I would just pump when it is convenient for you, or when you need to if you get engorged. I think ... [snip!] ... Any tips? My LO will be 21 months when my next arrives and I have a feeling that she is not going to wean before then."
I ended up pumping twice when I was away. I got a lot less milk then I expected thought (about 5 - 6 oz each time). It was so nice to be away. My son even slept through the night, that was great! I just wish he'd do that at home
The first few days of tandem nursing were great. I did have some clogged ducts though, and those were painful to work though. My milk came in very quickly. The baby did not have a very good latch and it was painful, but since there was so much milk and it came so quickly, he only nursed for about 10 minutes at a time (but very frequently).
My older child wanted to nurse all the time too. For a while I let her nurse every time she asked but I would become overwhelmed in the evenings (the baby would nurse very, very frequently in the evening and I think there was less milk then). I had to cut her back to about 5 times a day (for my own sanity). She was only nursing 3 times a day before my son was born.
I also found the sensations overwhelming at times, so after the first few days or weeks I nursed them alone most of the time. I spent a lot of time nursing and there were times that I felt guilty about not getting other things done around the house (like dishes) but it got easier as time went on
Best of luck to you.
