For one night a week? DP works late and DS is asleep/going to sleep when he gets home most nights. AIBU to tell you that he is still up?
and that this isn't the first time he has been up this late? He and daddy are in the bath right now and are having a ball i'm sitting down stairs listening to the laughs they are having and I really think DS needs this time as he adores his daddy (DP started this job recently and used to work from home so DS was used to him being around). I'm not sure what to do about it.
