I am often talking to families about "signs of wellness" for their little ones, since most people don't have (nor should they need to invest in!) super sensitive scales to see how much baby gets at each feed! I spend a lot of time reassuring parents that baby is well ;) So, what are some of the thing I look at to determine this?
Weight gain around an ounce a day in the early days
Back to birth weight by (in and around) 2 weeks
Plentiful wet and dirty diapers - especially lots of yellow seedy
A baby who is content and relaxed after a feed, and has at least some stretches of time between feeds (some cluster feeding can be "normal" but ideally not 24/7!!)
A parent whose breasts feel comfortable after feeds
Overall, an alert little one who is growing and meeting milestones well, according to their doctor!
