Laura, I BF throughout PG and tandem fed for about a month until K self-weaned. I had sore nipples on and off but it settled down. K would just postion himself around my tummy for day feeds, for his bedtime feed we'd lie down. If you find things difficult you could get your DD to sit next to you, facing you, and feed like that.

Tandem feeding postions - usually we would do the twin/football postion, one on each side. Tandem feeding can be a wonderful experience. I loved having a baby on each side. K would look at J and reach over to hold his hand or pat his head. Gorgeous!! It can be a great way for siblings to bond and also a good way to keep a toddler occupied when the newborn has to be fed LOL.

Good luck!
