My DD will be 3 months old in 5 days. Up until now, she's normally just nursed at one breast per feeding, and has gained well. Yesterday she started wanting both breasts (ie, she'll fall asleep at the first breast, wake up when I go to burp her, then want more so I'll nurse her on the other breast). Still plenty of wet and poopy diapers, seems satisfied after the 2nd breast, she sleeps in bed with me and nurses on demand at night too. I've been on the minipill since 7 weeks pp. I'm wondering if this sudden change in her feeding is due to a growth spurt, or should I be worried that my supply is decreasing? If it's the latter, I don't want to go too long without dealing with it.
