I am not a mum yet but i do remember both my parents saying it alot to us as youngsters.

It was met with a response from me saying "i love you too 150 times and just a hundred". I still smile now when i think of it because i loved them so much ( and still do ) and 100 and 150 were the biggest numbers I knew at the time and it was the absolute most I could love them. lol

I'm actually a little embarressed posting this as i have never told anyone else about it before but i did post it because i think that saying I Love You to your children is the most precious thing ever! Keep it up xo
