Chin bibs: I only used these for a while when DS was drooling like mad - teething - and to let him go with out one meant he got a bad rash under his chin in his neck folds. Otherwise, I skipped them as they cover up the cuteness of what baby is wearing! also, I'd have to wash either the bib or the clothes anyway, so what is the savings there?
BF babies spit up plenty! maybe no my DS, but I know plenty that do, especially if they have food intolerances. still I just use those flannel blankets for burp cloths.
as far as sheets go, I think 4 is plenty, but we never had much issue with DS leaking or spitting up or whatever on his sheets. I change his sheets out maybe once a month, just to freshen them up. I will admit to wanting sheets of different materials, like flannel - I love the flannel crib sheets - and I have a plush fabric one. I'd love a cotton jersey for summer. But that is just personal preference. FWIW we never bothered with those sheet saver things. I do have a mattress pad but that is because when my dad built the crib, the measurements were off a bit and no standard mattress fits, so I had to duck tape some foam cushion to the mattress to make it wide enough and the mattress pad helps that all hold together. It's only a couple inches, but totally necessary. I want a custom mattress but those things are wicked expensive.
Work shower went well, got 'sposies (add them to the collection :) ) and wipes and a few other things, and gift cards! yay for gift cards! (which no one writes the amount on, so you have to look it up) ugh.
Carrie - yay on your walk and having a good day!
I haven't heard good things about Walmart 'sposies, but I like the Target ones. and Walgreens brand is also good.
back to work, DH graduates massage therapy school tonight and I need to get cracking!
