It is tough to say without knowing the full situation of your sister-in-law. I do think you are being logical to want to keep things for your future use, especially big ticket items and items you have gone to lengths to take great care of in order to reuse. I totally agree with the advice you have been given in regards to big items you still need anyway like crib, stroller, highchair, even many toys. I also think that giving certain items to her, given the small age difference between your son and the baby to be, is somewhat illogical thinking on their part. My son is 2 and still in his crib and many cribs convert to toddler beds so they will need a crib of their own long before you are doing using it with your current child. I still use our stroller on a regular basis and he is 2, we still use the highchair, and just recently decided that some of his earlier toys are no longer of any real value to him, even simple toys can still be learning toys for a toddler if they are taught to use them in new ways, so they will need to acquire all these things on their own. The swing is the only thing, other than maybe walkers, or jumpers, that I think you might be able to part with. And honestly those things take a lot of space to store and if you have the money, newer better versions come out all the time that you would quite possibly want to get the newest and best of those for the new baby, if you had one, anyway. So if you could part with those things, which can be pricey you would be a generous giver and still be keeping the stuff you would really want to use for yourself. Maternity clothes I held onto myself, because they can be pricey and if you bought traditional, classic stuff rather than fadish styles then they can certainly be useful again in the future. Also, if your sister-in-law isn't the same size as you then she wouldn't be able to wear most of it anyway. Maybe buy her a Bella band ($25 online) and she could extend the life of her non-maternity pants and wear it practically everyday without needing maternity stuff until she gets really big and then she could pick up cheap large size pants from goodwill and use the band to hold those up (much of my favorite maternity pants are actually not maternity at all but larger sizes that I use my bella band with) and the band would help her feel comfy post-partum in her regular pants. It is like an entire maternity bottom wardrobe for $25 bucks, what a deal!! shirts are no biggy, she can raid her hubby's closet for tops as she gets bigger, no need to spend money. Kids clothes are touchy. You might be able to reuse yours if you had another, you might not. If you had a girl or if you had a boy in the opposite season you couldn't reuse anyway, but the same goes for her, plus add in a different genes factor and even if she has boy born in the same season she presents an entirely new set of genes into the picture and baby might not even be able to fit any of the stuff your son wore, so I would hold off on passing down that stuff until the baby is born. Besides she can get super cheap baby clothes at Josephine's closet next to the crisis pregnancy center downtown. everything is under $2 I think, maybe it is just $1 though, and to top that they occasionally have 1/2 off sales!! so if she doesn't live here offer to keep an eye out for her once she knows what sizes she will need and she get clothes at next to nothing (they have some nice stuff-it is all donation- which, by the way, if you decide not to keep your old baby clothes is something to consider). As to being selfish- only you can answer that. There are very unselfish reasons to hold onto some of your things, but your reasoning behind holding onto them is what makes you selfish or not. That is between you and God. So only you can answer that. I don't think enabling a person to be lazy is good if indeed laziness is the only contributing factor to their financial situation, but if it is not, Christ's example was to give everything you had to help out another - so giving out of abundance and the things you don't really need or really think you would reuse anyway is the right thing to do. If you decide to hold onto your stuff, check out Josephine's closet and get her a bella band and you have helped her a lot with minimal expense to yourself. Hope this helps.
