I wanted to get one thing after the first scan once we passed the 10 week point because I was paranoid about miscarriage/MMC before that point. Then I know DH was really reluctant to buy stuff but I started researching and assembling pinterest/amazon lists because I was going crazy and I wanted to buy but didn't at the same time.
I decided that it would be important to get the pushchair and car seat decided early on so that we could keep an eye out for deals, so I got researching on those and had my shortlist by 15 weeks. We actually managed to find my top budget one second hand later on for a real bargain, so I'm glad we did this.
The lists were also helpful because when we started to tell people, we found that offers came in of free/cheap used stuff and I was able to say yes we have this, we need that, etc, and could slowly tick things off the list.
I think we had everything by about 30 weeks barring some items like nappies, wipes, shampoo etc - I still have a couple of those things to buy but nothing massively urgent, and I've done another little clothing order this week as I couldn't resist but I think I'm going to go over the list and say stop now! Just put together things for the hospital bag and if we have forgotten anything then we'll have to buy it later.
I like taking advantage of sales and offers and things - we've literally spent €357 and that's EVERYTHING we could have possibly needed bar a few more nappies, some wipes and baby bath wash (and they even say that isn't particularly necessary) - and I will probably need to get a couple of breastfeeding-friendly tops but I will check mine and see what I have already.
Then some nice-to-have items - the adapters to put the car seat on the pram, car seat base DH wants (literally, the second most expensive item
) and some more clothes which I just think are cute and some specific books that I want. We have been given a few items as gifts but mainly this is shopping around for discounts, finding hand me down freebies and second hand items. We will still have a couple of bigger items to get as the baby gets bigger but for the newborn period, we're good.
