DP and I have a 10 week old son. DP has an older sister and younger brother. BIL is expecting a baby later on this year with his (very casual) girlfriend. I like DB a lot, and like his girlfriend, although I have only met her on a handful of occasions.
Was round SIL house the other day, and we were talking about BIL having this baby. SIL then said, "well, you and DP can give BIL all DSs clothes when you've done with them, help em out and all that".
BIL and girlfriend don't have much money (BIL isn't working at the moment). However, I'm not sure I want to just give all of DSs clothes away, as I saved up to buy him lots of lovely clothes (spanning from newborn up to a year old) whilst I was pg, (we're not exactly rolling in it) and also DP and I want to try for another baby early next year, so would really want the clothes again, regardless of what sex baby we may have. I have thought about lending them to BIL, but he's VERY unreliable, and isn't planning on living with girlfriend when baby is born, so I prob wouldn't end up getting everything back... and isn't it extremely anal to hand them over, with detailed list of all clothes given? 
.
If DS was our last planned baby, then i'd be fine to give them to BIL. Also, it's not the lending of the clothes per se that I have a problem with, as a friend of mine is also having a baby soon and i've offered to lend her anything she needs (as it happens, she's declined my offer). I just don't reckon i'd get them back from BIL and girlfriend, and it would make me inwardly seething if I didn't/the got ruined, but would like to help them out in some way...
Am I being an unreasonable tight-arse, or do I have grounds to feel this way? - geniunely don't know!!
Have to pop out, but will be back soon to read your opinions!
