Two year old slowly grasping mommy is having a baby

Fb had a “siblings reactions” video, showing all these younger kids meeting their siblings for the first time, my son will be 2 and a half when his baby brother arrives, we have been pointing to belly and calling it baby, to the point when he thought at one point that everyone’s belly was called baby lol. We finally got a name for baby boy number three and we call belly by baby’s name “Logan” my son has a small speech delay but loves repeating, so he calls belly “woah—gan” he hasn’t gotten the letter L down packed yet lol, none the less he was watching very attentively to the video and was focusing then slowly but surely had the biggest smile on his face with a sparkle in his eye, we explain the best we can that baby’s in the belly, and its baby brother, and how he will be a big brother, today he was all over mommy and kissing and hugging and loving on my belly. Great signs that he will be an amazing big brother

*pictures for attention even tho mommy looks like a tired mess lmao*
