I have spoken to DH about this and tbh honest neither of us are sure if this is a good idea, or if we even would want to do it, so thought I would post here to see if anyone has experience of this.
General background - DH and I have wanted to go to Las Vegas together for a years, but last time I went (4 years ago, with mutual friends) he was supposed to come but had to cancel at the last minute (just before we got together in case anyone is wondering why I went without him!). Since then, we haven't been able to afford it, but are now in a position where we would probably be able to go next year. This would also be our honeymoon as we didn't have one when we got married (in March this year).
All good so far, except we now have a 5 month old daughter (also the reason we didn't have a honeymoon - she was only 7 weeks old when we got married). If we were to go anywhere other than Vegas we wouldn't even consider not taking her, but Vegas really isn't suitable for babies/toddlers. And as we want more children we are looking at 10+ years before we could go.
Has anyone gone away and left a baby of 15 to 20 months old? Would she cope? At what sort of age could she understand that we will be coming back in a week or so? (She would be staying with my parents, who we currently live with) Am I being selfish to even consider this? (I certainly feel it)
