I don't think you'll jinx it Thurl, I'm sure it'll be fine and hopefully having all the nursery stuff will finally let you get properly excited about having a baby instead of worrying about the pregnancy - things are going well so far
We've got quite a bit of stuff for baby already, but mostly because we aren't too fussy about needing everything brand new and my dad/step-mum had a baby a couple of years ago and knew we were trying so asked if we wanted them to save a few bits.
They're giving us a Moses basket with stand, which was hardly used because he was a big baby and was in hospital a couple of weeks so by time he came home they only used it a couple of weeks then decided to move him into cot. We also bought them their baby monitor when he was born, so they're giving us that back for our baby lol.
They swapped their travel system for a lighter stroller when he was only a few months old and we were pregnant at the time (later miscarried) so we bought the travel system from them really cheap (like £50) so we'd have been stupid to say no, and that's in the attic at the min. It's got car seat and isofix base too.
We also have another car seat suitable from birth with a sure fix base that's only been used a couple of times - we bought it for when we babysat because my old car didn't have isofix points. We'll use that as a spare or for people looking after baby (grandparents etc).
We've also got the complete tommee tippee feeding set because it was on a really good deal last time I was pregnant and we bought it then as well as a manual breast pump and a few little bits like Moses basket bedding, changing bag, baby bath etc
We aren't buying anything this pregnancy until after my next scan but then we will be starting the nursery
Wish me luck for the anatomy scan please, so nervous! Its tomorrow at 10am, hopefully we will be finding out gender.
