The swing was my best friend early in my daughters life. She slept in it every day. Usually one of her naps was entirely in the swing. It was a lifesaver ( tired new mommy saver). It was in our family room, next to the couch. Toby mostly stayed away from it. Made him scared. Rarely would I step out of the room. Maybe to the kitchen or bathroom. The thing is, they're strapped into those things with a five point harness...between the legs, from hip to hip and both shoulders to waist. Baby can't get out and unless you press in these tabs and click, you can't get baby out. This baby must not have been secured.
As for dogs and babies. I feel that I have the most kind and gentle dog. He's a 3 year old lab and he's wonderful with the baby, people, cats, other dogs, etc. I trust him around our girl, but they are never alone together and I mean NEVER. Not only the threat of a bite, but he's 85 lbs. He could hurt her accidentally.
