Re: So confused about having a 2nd baby???
my older son was almost 2 when I got pregnant. he was an active nurser both day and night, and extremely attached to me. when i got pregnant, he naturally started nursing less because of the decrease in milk. at the same time, i would distract him by offering healthy snacks or doing other things with him that allowed us to be close even without nursing. he did continue to nurse throughout my pregnancy until I was 39 weeks pregnant and then he just stopped on his own (probably because I couldn't hold him the way he liked and we had to lay down in bed to nurse since we didn't fit on the sofa anymore!)
I think that the pregnancy and baby can encourage the older one to become more independent. And by the time you get pregnany and deliver, he will be 3. They make great developmental strides in the transition from 2 to 3.
If you want to add to your family, don't hesitate because of the older child. Things always work out. While there may be a brief period of time that is difficult, I think that it will work itself out.
