It is so nice that your Yorkie is so loved!
I also keep track of where Bailey is... all of the time. These small darlings can get into mischief and it wouldn't take much to ingest something and get into trouble with their small bodies. Case and point - I had to visit a loved one in another province a couple of years ago and my daughter was home with him. She is around 25yo and I warned her about leaving her purse on the floor... and open
I got a phone call saying that everything is alright now, but she had to take him for an emergency vet appointment because he got into her purse and ate 3 birth control pills.
An expensive lesson for sure... $450! She now keeps her purse out of his paws reach! I don't wish to alarm you with this example, just to let you know that it is commended that you are very mindful of your precious Oli. With support here, I truly hope that you know that you are not alone and that you are able to enjoy your baby w/out constantly stressing about a worst case scenario. Being vigilant is a good thing, as you never know what could happen, but I hope that you are able to enjoy your time in the here and now with Oli.
