My 6 year old son has pulled away and doesn't like us to show affection to him now. Is this a common problem? This is his first year of school and so I can understand he'd be uncomfortable of hugs and kisses in public, in front of people, but he's the same way at home, in private. We've always been a snuggly family, but he resists our hugs and kisses, and doesn't like to snuggle, even at bedtime. What can I do? I want to respect his wishes, but I'm worried.
