When you choose a partner, you're not just choosing one for yourself. You're choosing one for your child.
But sometimes, when you're in love, you don't see the signs that could tip you off to a dangerous situation for your child.
The first thing to check when thinking about having your partner care for your child is the way your child reacts to him/her. While it's normal for young children to be upset when mom leaves, look closely at your child's reaction when being left with your partner. Does your child cry uncontrollably or shake with fear? Is this behavior consistent each time your child is alone with your partner? Has the child started to show new behaviors like bed-wetting, thumb-sucking, being clingier than normal or crying uncontrollably every time you leave the room?
If you see any of these behaviors, think about the potential safety of your child.
