I sarted when DS1 was to only a baby which is 4 years ago - business has gone really well but must say son is a nightmare which could be attributed I guess to lack of attention when he was a baby?? who knows?? I would suggest waiting if you can and spend more time with little ones unless yours are older or you really need the money or you have such a good idea and don't want anyone to get in before you?? I also don't work afternoons and do stuff with the kids and same for weekends and so try (in theory)to just work mornings and evenings when they are in bed?? but depends what your business is I guess. Good luck!!
