My wife spends more time with my kids than me and hence my kids are closer to her. They share everything with her but not me. This hurts me at times and I feel that they are drifting away from me. Please suggest me how do I avoid this.

try to get involve with them or make sure to make time, make a conversation during dinner or anytime of the day with them so they will feel that you want to join their company. you can also talk to your wife so your wife will give time for you and your kids. as for me I give time for my husband and daughter for playing and many more and we have time together as a family too.
