I'm 21 and have been with my boyfriend for two years; we've lived together for a year and have a 9 month old daughter. He also has an 11 year old son who, it seems to me, is with us ALL THE TIME. In reality, he is with us every weekend (from Friday after-school to Sunday evening), every Monday from after-school til 6.30 and every Tuesday from after-school til 6pm. He is also with us from 8am til 6pm every single day of every school holiday and inset day.
