When you become parents (whether that is for the first or the nth time), a specialized nurse will visit your home for 24-80 hours spread over multiple days to help with anything required. If it's your first, she/he will mainly focus on teaching (how to bathe a baby, how to give breastfeeding etc.). If it's your second or more, the focus will be more on keeping the house tidy (vacuuming, cleaning up) and helping with the older kids (getting them from school etc.). And all the while, the kraamzorger will keep a log of the baby (weight, temperature, how often it poops and pees etc.) to make sure it's healthy.
Seriously, I don't know how I would have handled having my first newborn without the hands-on-live-counseling kraamzorg provides.
