When are you guys getting the big stuff?

Third time mom here, so no shower for this little girl. Our other kids will be 6 and 7 when she’s born, so we don’t have a lot of “necessities” and will be buying some new items. For those in a similar position, when are you buying the big stuff (car seats, strollers, breast pumps, etc)? I’m 17 weeks and just feeling anxious to nest and get everything in order. I don’t know if it’s because time moves so much faster when you have other kids to coordinate, but I don’t feel like I have any luxury or time here 🤣 (and also nervous about shipping delays, etc- ordered porch furniture in February and still haven’t gotten it!)
