As a mama myself, I have a lot of recommendations. Everything I tell my friends about lives here:
For everything specific to your program, they are below. Happy nesting!
Revolutionary Swaddle, Houdini proof & so so soft (0-6 weeks, at least 3)
Transitional, helps with the in between (1-3 months, at least 2)
The goal, in use for the majority of crib life (2+ months, at least 3)
The goal, just for colder climates (2+ months, temp dependent)
Miku Smart Monitor: non wearable, easy sleep tracking, app access
Monitors: screen free, tried and true, on for the bedroom and one for about the house
Hatch: great for overnight diaper changes and feeds, can be controlled via app
Talli Baby: download this app to help keep track to pattern match
Sound Machine: no app to mess with, ability to add a second in the hall if the house is noisy
Blackout Curtains: baby's room should be as dark as possible, so avoid lighter colors
Blackout Film: continuing the dark trend, best way to eliminate light
Rocker: this is a personal choice given decor, but I'd prioritize power and plushness
Lightweight Pack and Play: fits in a checked bag, easy to set up
Slumber Pod: darkness on the go, ability to roomshare easily
Video Monitor: no need for wifi, plug and see
Mattress: improve comfort on the go, follow safe sleep always**
