Tonight, he gave me a big hug and kiss and then said, "too, too" and was bending down/squirming while I was holding him. I set him down since he was squirming all over and he quickly grabbed my baby belly and said "Lincoln (Wink-On) too" and gave a BIG smooch to my belly.
Totally unprompted or coaxed.
This might just be the happiest Mommy moment I have yet to have. Took all I had not to bust into tears.
My sweet, sweet Jackson you are such a nurturing little guy. Lincoln is one VERY lucky guy to have YOU as his big brother.
