We just seem to bicker at weekends about who should do what for ds. Dh works away Monday to Thurs and in London on Fridays so I know he is tired; the job and travelling are hard work. I am 12 weeks pregnant, feel sick constantly and for the past 3 weeks ds has been up either at night or at 4.30am (or both!) every night. I feel beside myself with tiredness. How do you and your other half get away from competitive tiredness?
