I’ll disagree with whoever said to keep formula on hand “just in case”, and here’s why:
There are virtually no emergencies in baby-feeding that mean the baby will starve to death in the time it takes to go to the C-store and get a can of formula. When breastfeeding doesn’t go well, it’s still rare that baby is getting nothing - in fact, the usual end of breastfeeding is the mother’s discomfort, unrealistic expectations, or peer- or family-pressure…and not baby’s nutritional status.
However, when it’s 3 in the morning, and baby is 2 or 3 weeks old and cluster-feeding for 3 hours at a stretch, and mom is so sleep-deprived that she can’t think straight, and some person, meaning to be helpful, insists on giving that baby a bottle “to let mom sleep”…when what she and the baby NEED are those hours of endless suckling that tell the body “I’m a growing baby, make more milk!”…one bottle of formula can spell the beginning of the end of a successful, exclusive breastfeeding relationship. Now, if you’re knowingly willing to take that risk in exchange for a couple of hours of sleep, then that’s your choice - go ahead, have ready-to-feed bottles, they’re reportedly gentler on baby’s tummy - but realise that in some mother-baby pairs, especially during a growth spurt in the early weeks, one bottle of formula can make the difference between mom “having enough milk” and mom becoming convinced she doesn’t.
I’m a firm believer that many, if not most mothers who “didn’t have enough milk” really would have, if somehow their supply had not been sabotaged, either by unnatural feeding schedules, or by supplemental bottles of formula.
One bottle of formula also changes the flora in the baby’s gut, if you care about that sort of thing.
I highly recommend misc.kids.breastfeeding for online 24/7 support for breastfeeding questions and problems. Try getting that kind of support from your doctor, midwife, lactation department at your local hospital, or the LLL.
And now I’ll change the subject, and suggest something nobody else has: cloth diapers for using as diapers.
I, personally, prefer the Mother-Ease brand - they’re adjustable, one size fits babies 8 lbs to 35 lbs (or, they fit my kids in those ranges). The setup cost is high, but the per-use cost, however, is very low by the time potty-training comes around. The nylon snaps are sturdy and do not fill up with lint the way velcro fasteners do. Mine - which outlasted my twins, and are now doing duty for my youngest at 17 months old - are finally so threadbare that I have had to sew homemade toweling doublers into them to add absorbency. And yet the snaps are as sturdy as ever they were. They’ll go into the trash when she potty-trains. These things were never meant to last for 4 years of non-stop use! I wash about once a week now…it was 2 or 3X/week when she was little. I find it no more burdensome than any other load of laundry, and no more work than carrying a heavy bag of used disposables out to the curb. And I never run out and have to make a panic run to the grocery store for diapers, either.
But, of course, there are a million gazillion other cloth diaper brands out there, from the now-commercial Fuzzi Bunz system, to all the WAHM-made diapers (some of which also have nylon snaps), to the high-quality Chinese cotton prefolds (4-8-4). Whatever you do, if you consider cloth, don’t buy the crap on the shelves at your local department store. You’ll just waste your money, and become convinced that cloth is as bad as your mom remembers. Buy quality. It’s worth it.
I loved my Snap-n-Go stroller. Mind you, I still have the darned thing (want to buy it? :p) and it’s no good once they outgrow their infant car seat. I dislike the weight and bulk of the ‘travel system’ strollers, personally.
I loved my portable swing (which I still have, want to buy it? I’ll make you a heck of a deal). I could carry it from room to room and take it in the car with me.
We sure didn’t use our playpen much. It mostly collected toys. I finally folded it up.
The best baby blanket I have, I sewed myself from two layers: polar fleece on one side, cotton knit on the other. I saw one of these in a store for a lot of money and came home and made one myself out of scraps.
Target carries microfleece pajamas in sizes up to 5T. They really are wonderful. Not too hot, as other blanket sleepers can be.
For swaddling a baby - if yours likes it, my youngest was done being swaddled by day 2 - you might buy a full-sized flat flannel sheet (thrift stores are great for this). Cut it in quarters and hem or serge the edges. These are much larger than standard ‘receiving’ blankets and are less likely to come unwrapped at the first determined wiggle.
Speaking of babies, mine’s just up from her nap. Gotta run.
