I think it's also thinking about what is worth investing in for the future.
We didn't bother with a bath, DD baths/showered with us, meant life was much easier. We did invest in some soft baby towels and flannels. We won't be bothering again. The odd time we've needed a wash tub, we use the washing up bowl.
How likely are you to be able to pop to the shops if you find BF too much for you. If your local supermarket is going to have the items in stock, it isn't worth rushing out and spending money you may not use. I picked a steam steriliser second hand at a later stage. However DD was finnicky about what teats she would accept so we tried a few different bottles until we found the one that worked, so it's not worth investing in a large stash in case they don't get on with them.
I think you will need more vests and sleepsuits, I picked mine up second hand mostly, eBay or nearly new sales. Snowsuits are brilliant and cosy and keep them all snug and warm.
What is the second hand market like in Sweden, do you have family you can have stuff sent to in the UK who will forward it on to you? Would they collect something if it was local? I save searches in eBay for local items to collect and I have made some really great purchases this way.
I also bought my sling second hand, but I also bought a moby wrap at full price, but was a great investment for me, I have an awkward bodyshape for most slings and great big boobies that get in the way.
I agree little and often does the trick. Second hand really doesn't hurt, DD has some gorgeous second hand stuff that really no-one would know was second hand. Except I love to tell everyone about my savvy bargain hunting skills.
Shoes are pointless until they are walking, in my opinion. DD survived in socks/tights for quite a while as she had tiny feet, even once she started walking.
