5. Play fast and loose with car seat rules.
Certain things that grandparents do are quite irritating, while others are downright unsafe. While car seat rules have changed significantly over the past half-century, that’s not an excuse for grandparents to decide that safely tightened straps or a rear facing seat simply aren’t necessary—and they shouldn’t be surprised if they don’t get to drive with their grandkids in the car if those rules are ignored.
6. Try to feed babies too early.
Just because grandma thinks their three month old grandkid is really eyeing that plate of bagels doesn’t mean parents should automatically concede. Recommendations on feeding practices have changed over the past few decades, and now most experts recommend waiting until six months for solids—meaning those delicious snacks will have to wait.
