I've been going out on my own to the shops most saturdays or sundays for at least an hour since lo was a week old. His dad is capable of looking after him, I am not the only one who can deal with shitty nappies or bottle feeds & imo, because of this my lo is more secure with oh & oh is more confident in dealing with lo when he is upset or ill, regardless of whether I am there or not.
IMO a lot of women complain about how they get no time to themselves or that their oh doesn't do enough for the baby but we really can be our own worst enemy as a lot fo the time we don't even give them the chance due in part to this misguided sens eof guilt.
OK I know some oh's are really crap about doing baby stuff but most blokes I know would love the chance to spend alone time with their lo & know how to be a capable parent.
So no, you aren't a bad mum for liking work & going out alone. It will make you a better mum imo as you will be able to get some stresses release whilst away from your baby rather than losing it & shouting or stomping at home. Repeat after me; having a baby doesn't mean you stop being a person
