So I just had my baby girl 5days ago and while I was in the hospital my in laws were in from Texas visiting so they watched my 16month old son. Well two days after having my daughter I learn that my son has developed Croup 😰 my in laws had to leave today and I'm staying at my moms with my newborn while my husband takes care of my son at our house. My question is how long should I keep my children apart?? Has anyone ever experienced this? I don't want my newborn hospitalized.
