I have been through this situation with my granddaughter. Yitzchak Shalom ben Shoshana Elisheva should have a refuah shelaima b’soch sh’or cholei Yisroel. It is very, very scary when it is a little pitzel who needs to be hospitalized. May all your worries turn out to be for nothing, and he should return home to his own crib and his ema and abba’s arms in 100% good health, b’korov.
