I feel loved very much. Of course I have a simple approach with this. I asked them "Do you love me?" and they say "Yes" or "Of course". Then that's settled.
Although last time I asked my first son "What is love to you?" He was lost for words (he's autistic like me). Then he said "I'm not sure what love it, but I know I love you."
As for me, I didn't really understand love until I was 30, had my second baby and fell head over heel in love with him. Then suddenly I seemed to have grown up, understood love, and loved other people better, too. I still feel maternal love is more "true" than any other form of love.
I agree, the love I feel for my son is unlike any other and perhaps the truest expression of pure love.
