Yeah, ikwym. I love mine too and held onto when i had dd#2. DD#1 was 2.5 years by that point so i decided to get a double as well on the basis that i would still mostly use the stokke with dd#1 and only go double if on a long walk. That worked well and was a great compromise.
Now dd#3 is due in 5 weeks and reluctantly i hve had to accept that i have to sell my stokke. DD#2 will only just have turned 19 months when baby is born so i have now bought a phil & ted as after lots of research have accepted that this is the most useable of all the doubles (easy to park in cafes, get through small shops etc) and will have the longest life span as can use as a single when dd#2 outgrows it.
Am sad at getting rid of my stokke tho. It is lovely. But will need a double buggy all the time soon with 2 under 2 so have to trudge off to ebay ! I suppose it depends on the age gap between your children as to whether or not you need to get a double or whether you can muddle along with the lovely stokke!
