Im really responding to the night out for dinners

You are very lucky to have a 6.5 weeker to sleep soundly at night.... darling it can change without warning so i wouldnt even be thinking of 'what happens when?' Babys at the age dont need baths every night for starters (except if they have had a huge poo/vomit) so if i were you if you want to go out for dinner go out now whilst you can easily. Feed bath wrap and if your lucky (like we were) put bub in pram and walk down to where you can enjoy a evening out. Dont go worrying about things that trust me like routines fall into place by them selfs with new borns.... I hope i was a help.

Oh and congrats at your new baby
