It’s OK to cry, and it’s OK to cry in front of or with your kids. It is good for them to see your vulnerability. You don’t need to be strong all the time. After all, the Bible teaches that it is in our weaknesses HE is made strong.
It’s good for them to see you experience sadness, empathy or the array of emotions that might be causing the tears. We teach them that although we experience sadness or pain in this life, we can always rejoice in Christ no matter how sad we may feel. God weeps with those who weep, and he can be our greatest source of comfort and the giver of joy. Life can be hard. It’s also a great time to teach that in heaven there will be no more tears. If you are feeling and experiencing this sadness too often, I’d definitely seek someone who might be able to help. However, if these tears are just the normal tears of being human and experiencing pain, it is really healthy for kids to understand these emotions are OK to feel as long as they aren’t a place we choose to stay for too long. Our hope in the Lord can overcome sadness.
