It took me awhile to get back here to check, but I'm soo happy to hear Sydney did well and should be coming home soon!! She'll most likely sleep a lot, which will be nice for you to just sit and love on her
If you decide to do the onesie, one thing someone on here suggested is to cut a hole in it for the tail, which I hadn't thought about. Lola hated having her tail covered, so it would be worth a try. Glad to hear she did well, and now you can breathe easier. Keep us posted on her recovery please.
Toby and Lola send get well wishes to her!
