Before or after pregnancy?

I saw the newborn pics of jr and thought he wasnt an “average baby”. But as he grew, not including the meowing, he seemed to be actually “GROWING” a bit. But recently it seems he’s reverted and gone back to being nearly a vegetable. Do you guys reckon this was because she drank during pregnancy, or because she’s somehow injured him when he was a few months old? Or maybe both? 😩I just seen a pic of him sitting up in his lil walker, smiling and all, and he’s defo regressed since then 😩
