One of the wonderful things about children is that they all have different personalities, even if they are similar, there is still something that makes them individual, and this is what makes me love all my children the same - because I love the different qualities that each of them have kwim? I know it is probably a shock to you and it is probably a big part of why you think you won't be able to fully love all your children, cause you weren't expecting to have to share yourself with another. But as your girls grow and change, you will find new things to love about them too, the things they do and say and their little 'isms' that make them like no one else.

This probably sounds a bit airy-fairy, but I do think that what your feeling is natural and in time, you may feel differently about all of it when you have had a chance to get used to the idea.
