I agree it really depends on bubs and how things work out, it's just not something you can know or plan for. My DS1 could be left no worries, he was on formula and put himself to sleep well and just woke for a bottle or two. DS2 is a whole other story, he will not drink anything from a bottle, not expressed milk...nothing!!! I did go to the Sex in the City movie just the other night, fed him to sleep but he woke & wouldn't drink from bottle for DH, he just waited up happy til I got home. He also wakes every 2hrs & only goes back to sleep with a BF....so no date nights for us LOL. But if you can GO FOR IT....a date night, a great idea.
