I have twin girls now aged seven. As much as you will love them you will have a nightmare with the stress of feeding, winding, changing nappies etc.
It gets easier after they are 2 and a half years old, until then, NIGHTMARE. Ohh and enjoy the baggy eyes you will get in the first ten weeks
Congratulations mate, Im very happy for you, see the double trouble you will get it as a blessing, it's the best thing in the world to have twins
