Such a relief to hear Teddy is much better!! I think any furrbaby can become jealous. Just like a human child. Hopefully the adjustment period with your newborn will get better. But you are right to never be to careful. Always better to err on the side of caution. I hope you will be able to pop back in once in awhile and let us see pictures and know how things are coming along. Once things settle down into a routine, of course.
Take care!
