Many 2 y.o. kids go through getting overly attached to mommy. It may be part of his normal development--unrelated to the SPD. Encourage your hubby to have some consistent activity he does with your son every day--no matter what, even if it's just three minutes before bed reading him a book. Two year olds thrive on routine, so building a daddy and him time into his every day schedule will be good for him and daddy (as well as give you a little break to take care of yourself--which we always leave undone it seems). I wouldn't be too worried about the soccer failure. Most two y.o. kids aren't very social yet. My daughter didn't really start enjoying playing with other kids until she was nearly four. She would play alongside, but not with. Now, at 5, she's very social and even asks if we can invite kids over to play. It will come when he's ready.
