We used to use those cheapo “umbrella strollers” basically as a last resort, when short folks were way too tired to keep going at the end of the day and our backs were worn out from lugging them when needed. When I had two kids of that size I tied two such strollers together to make a double-seater. At $19.95 each brand new (and much cheaper in garage sales) it was most cost-effective.
The strollers I see out and about now are the baby equivalent of Cadillac Escalades, while we had an old VW. In fact, now that my daughter can drive we bought her an old VW. When it won’t run, usually a hammer, some duct tape, and maybe some paperclips will get it going again, which fosters creativity.
As to baby-proofing, I simply reversed the cabinets: Towels went under the sink and nasty things went into the highest cabinet I could find. I put a cheap latch up high on the doors to the outside so no one could suddenly dash out into the street, and I put a baby gate on the stairs. I also took the knobs off the stove, and they are still off because we have big dogs who like to check out the counters and they have accidentally turned the burners on.
We did buy a crib and a playpen for the first baby (we ended up putting the Christmas tree in the playpen because we got tired of picking the plastic ornaments up all the time), and someone gave us a used high chair. However, we never had a changing table, or a fancy diaper pail, or toddler beds, or many other fancy doodads. Instead, we spent our money on books and doing things with the kids.
For baby number two, though, I did get one of those front pouch baby carrying things – that was a godsend since I had a newborn and a two-year-old at the same time.
We used to get a lot of compliments from older folks who said they enjoyed seeing our kids being able to move about and be kids. We let them do that as long as it was in an appropriate place and time.
I suspect some of the escalation in childcare accoutrements is simply a result of marketing attempting to make new parents feel as if they have to have all those things, and partly it is the inevitable feeling that new parents have that they need to give their kids everything (big mistake!).
