Hugging and kissing on forehead is fine if you see your son after a month or so.....
so now wife will decide the "time limit" for kissing on forehead by moms/dads ...... aaah ridiculous... just think you are meeting mom after 47 hours and as soon as she is about to kiss and hug you wife goes "no no ammi ..abhee 47 hours howey hain, you can kiss him only after 48 hours.,,,while i can kiss him right left and center"
...and then they (girls) say they have tonz of complains with in laws. Off course if you beheave like this you are gonna have complains. Make your life easy girls. Let mom show her love to son ... she will not take him away from you.
