I just want to say congratulations on your pregnancy! You will get your head around it soon and you will be very excited. In my case, I have a 2 year old and I 16 weeks pregnant with my second and I too was worried about how I could love another when I am so in love with my DD! But let me say, when I went for my ultrasounds with this new baby (its a girl) I had all this emotion flooding back to me of joy and excitement. Just because it is your second, it is just as amazing and special. I love this baby already with same amount of love I have for my DD and I can't wait to meet this little bundle of joy! I hope that makes you feel better.
