Cats....Keep or give away? Please Help!!

I really love my cats but I don't know what to do. I have had my oldest cat her whole life she's almost 8 the middle one which is her son he's 5 and our youngest cat is 2. I am expecting my little boy to be here in 3 weeks me and my husband just moved into our new house. We have not brought them here yet because we are deciding what to do. They are at our apartment but we need to get them out soon so that we can turn the keys in. I love how the new house smells how clean it is how hair is not everywhere and it's just ready for the baby to arrive. It feels good to not have to worry about the scratching of the funiture the stops the get downs the hair the smell of litter everything and also not having to worry about how they would act around the baby. My husband thinks 3 is to much which I agree but something insides me just wants to get rid of them but it makes me feel so so sad of the thought of not having them. We have gone through furniture twice going on 3 because they have damaged and scratched couches chairs carpet we can't keep anything in good condition. I think the oldest girl will be heartbroken and so will the 5 year old but the youngest I'm not to worried about even tho I love him as well. I don't know what to do I love them but it's such a huge life decision declawing is to expensive and we can't afford that right now I need to know what to do tommorow. Sad to say I can't find anyone to keep them so it would have to be the shelter ..I'm so confused please help?
