Believe me you will love them equally but very differently one of the things I love so much about my 3 monsters is they all have different qualities which make them special. When I was expecting my second I felt the same things and I am sure most if not all women do and probably the men aswell.
My eldest was very jealous at first when we had our second son and refused to come near me for about a week he was punishing me because of this interloper, but we made sure he felt included we got him a present that was from his baby brother and gave it to him when he came to visit after the birth, and we gave him little jobs to do to help mummy and his baby like fetching a nappy or babies coat.
If you are having mummy and Kade time make sure your OH has the baby and knows not to interrupt so Kade doesn't feel pushed out. Also don't try and make any changes in his life like going to a toddler bed or toilet training at the same time.
