Sure, I can help with that
Most people will buy diapers and wipes but I always put it on my registry especially if you like a certain kind. Huggies always were my favorite. On my registry I had outfits and sleepers (In my case I got more 0-3 than newborn) My kids were fairly big so we went through newborn clothes super fast! I asked for wash cloths, burp rags, crib sheets, blankets, pacifiers (which I never used because neither kid took one lol), bibs, diaper bag, baby shampoo and body wash, lotion, diaper rash cream, baby nail clippers, thermometer, gas drops, and monitors. That was about all I had on mine as far as little things. I did ask for a few bottles although I breastfed both times but I still needed them when I was away from the baby.
Some of the bigger things i had on mine were car seat, stroller, and changing table because my mom and dad told me they wanted to buy the big stuff. I mainly just put it on there to give them an idea of what we wanted. We bought the crib and most of the clothes. I also bought my breast pump and storage bags. I just felt weird putting that on my registry lol although some people may do it, I'm not sure?
The things I got alot of that I never used all of were burp rags, wash cloths and bibs lol. I had 30 of each I swear! And someone got me a diaper genie and I didn't like it because once it got full and had to be taken out it was just disgusting. We normally just put ours in a walmart sack and take it straight to the trash outside lol.
