Leese basicly our plan was to put every single that would be needed and then whatever was missing me went and got. Which was absolutly nuttin since we got everything LOL. As for ur must haves checklist here's what i think:
-Diaper genie (if your going the standard diaper route..which i most definetly am cuz i'm sorry but having to constantly wash clothes diapers?? 'shudders')
-Johnson nightime bathtime shampoo, creme etc kit
-Stroller and car seat ( i strongly recommend something similar to what we got cuz it is freakin amazing! 3 wheel like bike wheel one
-Baby toys of your choice
-Highchair
-Baby bumbo
-Playpen
-Nursery sheet set
-Crib
-Change table
-Change table pad and washable covers
-Exersaucer play station
-Baby blankets
-Bouncy chair
-Set that incluede's baby thermometre, hairbrush, tooth brush, nail file and clippers etc
-Pacifiers for different baby age
-Bibs
-Burp pads
-Sounds monitors (i recommend the Angelcare ones with the sensory pad)
-Sophie the giraffe teething set (it is the freakin best of it's kind)
-Sleep sheep sleeper (i started puttin ours on my tummy and Charlie already goes crazy for it)
-Baby powder, Sudocreme diaper rash, baby oil etc
-Baby play mat
-diapers
-diaper wipes
Hmmm...off the top of my head those are pretty much the main things i can come up with..althought there are a ton more LOL
