I agree with having your daughter stay with the one of you who's not currently in confession. At her age, she is old enough to pick up on words and/or ask you about them.
When I was very nervous in confession (I still am, but it's not as bad), the priest taught me a simple Act of Contrition: 'Lord Jesus Christ, Son of God, have mercy on me, a sinner'. I have used that ever since and no priest has said that there's anything wrong with it.
I sometimes do go with a list of things I want to confess, but now that I'm going more frequently, I usually only have 2 or 3 things, and I can remember them.
I'm glad you and your husband will have the opportunity to attend this sacrament.
