My 3 yr old gets the smiliest smile on her face whenever her dad and I hug, even though it isn't often. They need to see their parents affectionate. It is like I hold one end of a hammock and my husband holds the other end, and our daughter sits in the middle. If her dad and I do not seem close, it makes her insecure; what if one of us drops our end? It is like that, I truly believe.
It were better for him that a millstone were hanged around his neck, and he cast into the sea, than that he should offend one of these little ones.
