Some ways to find scales - the key being find A SCALE and use the same one all the time because scales are different... my pedi's scale is 1/2 lbs off from the scale I like to use.
If you want pounds and ounces instead of 1/2 lbs on the home scale...
Got a market? The produce guys at the fish market, farmers market, hfs usually think it's fun to weigh babes.
Nearby hospital or community center? Anywhere there is a breastfeeding support group, the LC who runs it almost always has a scale there. Free, and a social opportunity if you want to see other bfing moms.
Ask the pedi/fp. My pedi is ok with me stopping in to use the scale "regularly" - which I interpreted to be once a month if I wanted, since we skip most well baby checks.
What's in your community? MY vet's scale is calibrated to 1/10th of a pound. She's cool with us going there too, it's one of those hold the baby and weigh yourself and subtract the difference things. But a lot more exact. We tried this at the last doggie checkup, she said we could use it anytime.
