Just started TTC baby #2

I am 23 and just stopped taking my birth control this month to try for our 2nd and last baby. I have so many mixed emotions. I have a 5 year old daughter that I had when I was 17. I have been a stay at home mommy since the day she was born so she is my best friend and most favorite person in the world. One of my biggest worries is that I won't love another baby as much as her...or that I will not have enough time to give them both the attention and love I think they should get from me. I am so excited to experience pregnancy as a adult and not a teenager and for my girl to be a big sister because she just adores babies.
