Too young for crying
A 2-month-old baby is still too young to be left crying
Parents should still do all the things they need to do to console the young baby. They should be sure the baby is not too hungry, not too full, not too cold, not too hot, not sick, not wrapped too tightly, and not too lonely. After the baby turns 3 months, parents can start stricter "bedtime" routines, as by then, most babies can be trained.
