Here are some 'clues' that your child loves you .. from the excellent BabyCenter website ..
1 Your newborn stares into your eyes.
He's actually working hard to memorize your face. He doesn't understand anything else about the world, but he knows you're important.
2 Your baby thinks about you even when you're not around.
Between 8 and 12 months old, she'll start to scrunch her face and look around when you leave the room — and she'll smile when you return.
3 Your toddler throws wicked tantrums.
Nope, those screaming fits don't mean he's stopped loving you. He wouldn't be so hurt and angry if he didn't trust you so deeply.
4 Your toddler runs to you for comfort when she falls down or feels sad.
Kids this age may not truly understand the meaning of "I love you," but their actions speak louder than words.
5 Your preschooler gives you a gift.
A flower picked from a garden, a finger-painted heart, a sparkly rock, or another small token is his way of saying you're special.
6 Your preschooler wants your approval.
She'll start to be more cooperative around the house, and she'll look for chances to impress. "Look at me!" will become a catchphrase.
7 Your grade-schooler trusts you with secrets, like his first crush or his most embarrassing moment.
You're his confidante, even if he shies away from your hugs in public.
And here are a few more that I could think of ... remembering my two year old daughter ...
Feel free to add more in the comments section :)
Your preschooler repeats everything you say.
Even if words don't make sense to her, she (tries to) repeat everything you say ... goal, sixer etc.
Remembers your likes & dislikes
