This is something I have been thinking quite a lot on from time to time. Is it ordinary among your and your friends families that you say once in a while that you love your parents/kids or is it something I hear mostly on TV ?

I can't recognize that I ever said this or that I got any tells from my mum or dad.

I talk to my parents frequently and I always tell them that I love them.  My wife and kids......ALL THE TIME!

My mother-in-law, well......I'll just leave that alone.

My Mum has only ever said it a couple of times... my Dad never.

I say it to my kids every day.. I think it's important that you tell your children that you love them.
Even when one of them is upset with me and tell me that they hate me, I normally respond with
"Well, I love you"

My daughter always wants it to be the last thing she hears whenever she goes somewhere or
speaks to me on the phone, for the simple reason that if something were to happen to one of us,
that would be the last thing either of us remembered as saying to each other. 

I say it to my folks and the rest of the family all of the time.   While I am very sure my parents love me, they don't say it often.  It is a generational thing, like the guy hug.    You would never have seen that years ago but today it is pretty common.

I tell my wife and son at least once a day and my mom everytime we talk.   It is soooo important for them to hear that and see it as well.

Absolutely... I always think that, heaven forbid something happens to parents/kids, and you never see them again, and then regretting forever that you didn't let them know how you feel.

Of course. 

My folks know how much I love them.

My wife, parents and four kids are the world to me.

Great kids RodgerDodger  The second there peaking out from behind the first one looks EXACTLY like you!

They are cute.  Two is enough for me.
