We focused a lot on functionality and ease of use - wanted stuff that would actually be helpful and not just fancy.
For stroller and car seat, we went with the Nuna mixx next and Pipa next. Love how they click together and are so easy to maneuver and adjust. The big wheels on the stroller are a huge plus for us as we live in the city and navigate some tricky sidewalks. Also, the bassinet option has been fantastic - our baby loves it and it makes it so easy without needing an extra purchase. We got the ergobaby 360 carrier which is super comfy - the curved straps distribute the weight nicely across your shoulders and back, especially helpful now that baby's getting heavier!
Our other must have has been the Babysense play mat. The different toy attachments keep our little one entertained and it's machine washable which helps because of all the drool/spit up. We also love the kick and play piano - such a fun first instrument and keeps him engaged!
Other things we've found helpful are a rock n play for the overnight sleeps and the Fisher Price Papasan swing for some daytime naps.
We've been pretty minimal with our purchases, focusing on what's really useful vs fancy gadgets - would definitely recommend all of the above!
