M.W.
L.- I felt the same way when our second daughter was born. We had a 2 year old who had never been left with anyone or babysat for any duration of time without either my husband or I present. I stressed about my parents ability to watch her and timing since they live far from us. We ended up asking some friends from the Kingdom Hall that we attend. They are an older couple who don' t have grandkids of their own, but our daughter was somewhat familiar with them and they did great. I, like you, wanted my husband in the hospital with me AT ALL TIMES! Even though it was the second time around I still wanted that support. If you have some friends in the area that you think might be up to the task, maybe have some play dates where they can get to know your toddler and visa versa- that way when you call them up on D day, maybe it wouldn't be such a shock for child #1 to go to your friends house for the night. Also I don't know about your hospital, but the nursing staff was very friendly and attentive where I delivered in case your husband did have to leave periodically to check on your toddler.
I remember feeling like nobody could care for my child the way I do and I remember thinking she would be balling the whole time we were away. It turned out that she had a blast and developed a close relationship, almost like another set of grandparents, with the couple that watched her while we were in the hospital. Your situation sounds kind of different than ours, but I thought I would share my story with you. We got a surprise and found out we are pregnant with #3. I kind of worry about leaving #2 overnight since she's not done that very much. Hope all goes well.
