First, congrats on your new baby.
Next, you can AP even if your child has special needs, it's even more important, IMO. Having a SN child really puts the emphasis on the *attached* part of the AP 'label' (which I really don't like labels). Having a SN child made me question nearly every single thing I do, almost on a daily basis. You have to balance what your instinct is with what you *know* you have to do. Yes, things are different, but you will adjust. You will love him. He will know that. You do what your child needs, even if it doesn't fit into the checklist of 'ap'.
Hang in there. Again, congratulations! He IS a blessing.
