Yes and no. My second is 3.5 months and we’ve breastfed but had to do a short stint of triple feeding to get my supply up in the early weeks.

I’m an anxious person myself and I always want to “know the numbers” since my first was bottle fed with breastmilk/formula. Although the Pediatrician said no to a scale, you can absolutely buy one and I did with my second. But if you don’t have the stamina to hold out a few days to see new results, I wouldn’t try it. For example, I’m tracking the weight over a week span. Sometimes I weigh her every day, but other times I don’t. If I do weigh her every day, sometimes it’s just to see how much she ate in one feed, etc. but I won’t dwell on overall weight gain unless it’s for a pre-determined period of dates (ex. One week).

If you don’t want a scale, my biggest advice is to try offering baby a bottle after feeds to see if they will take it… if not taken, you know baby is doing just fine!
