I got whats on sale and what affordable with everything. Your baby will be just fine either way.
I tend to stick with pampers for diapers and wipes because they are cheaper and they have less of a reputation for causing rashes than huggies. Ideally I'd use honest company though. And for car seats I recommend graco. I have all graco products including the forever car seat which I use with my nephew as well and graco bucket seats. Its all up to you, but those tend to be the brand's I trust.
Diapers I've always used pampers for newborn because they have the peeline on it which is perfect when ur unsure if they've peed or not when they're that little..but as my boys have gotten older and more squirmy Huggies little movies I found were the best...diapers are one of those things that you'll decide which ones work/fit better for ur little one as they grow (no right or wrong)...when it comes to wipes i love the Kirkland brand which is Costco (not sure if u have a Costco)...i had Graco for my first 2 but only because it was affordable. This time around my guy splurged on a jogger/carseat combo. Just go for things that YOU like/want and if you have any concerns about the product google reviews on it then make ur decision after...also when u make ur big ticket purchases make sure to always ask about their return policies :) happy shopping
I found that diapers depend on the baby as my first couldn't use anything but pampers and the next three couldn't wear pampers. My friend just had a baby and says she wishes the honest diapers were softer. As to carseats it depends on your preference, I like Britax but then that's what a lot of my family has used for 30+ years
I just read the reviews of the products. I got for the affordable products because they aren't going to be used more then a few months. But everything I got was under 100 dollars for the product. Had great reviews (more then 100). Other then the car seat and stroller bundle which was a surprise from my husband and he used his credit card reward points. Chicco is a great brand....seems like Graco has a lot of recalls. But that's just from what I've seen. I also have gotten a few ingenuity products (very affordable) and love the products we've purchased through them. For my nursing pillow I got a great one!! It's a Fisher Price 4 in 1, and I find it to be so much better then the other brands PLUS it grows with the baby.
