This is a difficult question to answer, particularly if your young child or baby's time is being split between parents or caregivers who aren't together. Unlike babies between 4 and 7 months old, who in many cases are still breastfeeding and therefore spending most of their time with their mom (or maternal attachment figure, in attachment theory language), toddlers and young children have a greater emotional and physical capacity to spend time away from parents. However, this still doesn't mean for long - studies have shown that even emotionally resilient children who spend a week or more away from their primary caregiver frequently develop separation anxiety, and subsequently have an insecure attachment to their caregiver.
