My daughter, who is now 33 mos old and tandem nursing, was nursing about 5 times a day while I was pregnant. My nipples got sore a couple of times, because the milk supply does dwindle some while pregnant. I suppose the taste of the milk changed, with all those new hormones, she only made faces, but continued nursing. Just keep doing what you were doing.
Nothing needs to change.
I had some spot bleeding and found my cervix to be soft around 6 months and was advised to wean her, but I didn't. After our little boy was born, we kept up with the nursing. Most of the time I had one on each breast, which turned out into a laughing party. They are the happy nursing couple. No Messages Hi.
