Congratulations! You’re registry looks pretty good.
I personally would highly recommend a swing, we didn’t get one till our 1st was 2 months, and it really was a lifesaver for those times when baby just needs to be rocked and you need to get dinner or go to the bathroom.
Diapers! Are definitely essential and the biggest help, it can get expensive and you don’t know how long a baby will be in a certain size especially at the beginning, so it’s nice to have a few different sizes before baby shows up.
Boon bottles. Even if you plan on breastfeeding it’s nice to have a bottle available if someone else wants to feed baby, or if you get sick and need to take some medication, etc. you never know. For us we tried to find a bottle that ‘mimicked’ breastfeeding and we found boon bottles worked the best for us, however there’s a few different brands that people swear by.
And also recommend putting a few different types of pacifiers, so you can try them out and see which one works for your baby.
*Edited to add I’d also highly recommend the woombie swaddle or something like it has no Velcro that will wake baby up in the night, and if your baby is a mover won’t come untucked like a swaddle blanket.
**also this might sound weird, but adult diapers for postpartum made my life so much easier, no stained clothing
