My kittens keep going in the bottom storage part of my babies bassinet, I can’t keeep the kittens out of the room, is there any way to keep them out of his bassinet? I pull them out and give them a good slap everytime, but they don’t care and keep going back, they’re only 8 weeks old, I feel bad, theyre so cute, but theyre getting claw marks in my baby blankets

As you have already noticed, your method has not helped. So stop hitting your kittens. Slapping a kitten is not like spanking a child. Kittens do not understand enough spoken language to know that they have broken a rule and are being punished for breaking that rule. All you are teaching them is that you are willing to hurt them. Here is an article that will tell you about more effective ways of training cats: http://www.perfectpaws.com/train.html

It is in the feline nature to look for small, enclosed spaces to hide and sleep in. That storage area appeals to them on an instinctual level. There are operant conditioning methods that could possibly succeed at training them to stay away from that particular spot, but it takes time and persistence. But I would guess that it will be a better use of your time and energy as a new mother to deal with it on a more practical than behavioral level. So you are either going to have to modify the bassinet to keep the kittens out of it, or you are going to have accept that the kittens are going to get in there, and move the blankets to a drawer or closet that the kittens cannot get into.
