How did you find out Rosie?

We will most likely have another, the question is just when. DH & I always wanted a big family, especially DH who wanted them all close together. Realising now the responsibility & financial burden, we shall see. What I wonder is will I ever sleep again, and how will I cope with a baby & toddler. DS is a good sleeper, but I've always needed lots of sleep so I've found it hard. How long does it take to adjust to less sleep?
