two questions actually

Question
QUESTION: I have a corn snake, shes just over a foot long now and in the past two weeks she has been throwing up her food, we feed frozen pinkie's. when we first got her she would eat up to 4 of them and has gone down to one??? help.

Next question, we recently added a baby ball python to our additional family and he went through a shed about a week ago and it took him a long time to get through it [not complete shed] and he's in one again? he won't shed properly and it takes him the longest to get his shed off his face? what can i do??
thankyou!!! can't wait for your reply

ANSWER: OK, the corn needs veterinary help.  Regurgatation is bad!  Also, once she's back on her feet increase the size of the prey, not the number.  At one foot long she could easily eat fuzzies if not hoppers.

As to the ball, you need to increase the humidity in the cage AND provide a water dish large enough for it to soak in.

QUESTION: the ball has a big water dish and we spray the cage down 2 times a day
we've been taking him out regularly and been giving him baths in the sink and using shed aid on him but nothing seems to work

Answer
Babies shed often, especially if they are feeding a lot.  But what you describe could also indicate an endocrine problem as ecdysis (shedding) is under endocrine control.  If it's truly a baby you might have one with a bad endocrine system and the odds of endocrine malfunction would increase if the snake is not a baby.  I don't even know if vets can test for that in snakes...  Help the snake shed out any extra skin AFTER it has shed what it can on it's own.  If the problem continues talk to your vet.
