Shakira raised eyebrows when she brought newborn Milan to a soccer game in Barcelona to watch his pop play. Was it a mistake to take her baby to a crowded soccer stadium? Depends on who you ask. Your abuela may take the traditional view that newborns should be kept away from crowds because of the myriad germs out there. More modern thinkers might not blink at the idea of exposing baby to a crowd. But newborns have developing immune systems and aren’t yet vaccinated against certain illnesses, so they may be especially vulnerable. Parents should use caution and good judgment when deciding where to take them.
