First "baby" appreciation post (aka: pets)

In the quiet moments after our little human baby goes to sleep each night, our immediate attention turns to our "OG kids"- our sweet pups. My girl Lilly specifically is the first living being that was all mine and has been with me through it all. Our relationship has evolved a bit since my son was born, but she's still my first baby and I try to find ways to connect just her and I. A walk just the two of us or a car ride with the windows down like the old days usually does the trick. Who is your first "kid" and how are you/they adjusting to a human sibling?
