I'm 12 weeks today and im still nursing my 7 month old. at the beginning (before i knew i was pregnant) my breast were very sensitive. but it eventually subsided. I'm still lactating like a champ! i was so worried about drying up lol but so far so good. I'm hoping to tandem nurse, and ive also been really excited thinking about after giving birth and when my milk comes in my son can go visit and help me out with my engorged breasts.
