Well @Hallyup89, luckily for me my DH completely disagreed with your comments when our DS was born (with a heart condition, no medication).
Our DS would wake about 3 times a night at a minimum in his first couple of years. Feeding was little but often as his heart condition meant he used a higher number of calories just pumping the blood around his body than a healthy child. So he'd often be hungry during the night. He's still on the thin side despite eating more than my DH now (DS is 15 years old now).
DH would do a feed then I'd do a nappy check/change whilst he went back to bed, so we'd both get maximum bed time. Then we'd swap. His view was that DS was the most important thing and I needed to be alert to keep him safe every day. Not half asleep having had a bad night with doing all the feeding etc., He used to go to work on the train so had an hour of dozing to catch up in both directions. I couldn't take my eye off the ball for very long during the day. I was a SAHM so didn't go to work until DS was at secondary school - so maternity leave never came into it.
Friday and Saturday nights I'd get the whole night in the spare room whilst DH covered everything. I'd had a C-section and contracted an infection whilst we sat by our baby's bedside watching him fight for his life so DH wanted to make sure I stayed well.
He used to do the bath routine - I think I gave DS half a dozen baths in the first three years of his life! DH loved it as it gave him and DS time to have a giggle and splash about a bit. I'd start our dinner whilst he did that and we'd cover a bedtime story between us.
When DS got to about three years old DH travelled for work so would get airmiles. I'd cover everything then as he was away. But the routines were established, DS was thriving and he was in pre-school a couple of days a week so everything was easier.
DH would give the airmiles to me every 6 months or so and I'd have a couple of nights in a London hotel to see friends, see a show, mooch around shops etc. He was travelling to the area of the UK that he comes from so he'd see family and friends then so he didn't miss out. When I went into London DH and DS would go off to the cinema, swimming, visit a farm or whatever and stuff their faces with pizza in the evening!
They've got a great relationship - normal teenage angst a lot of the time but DS would do anything for his dad which is lovely to see. And DS finds it odd that some of his friends dads don't seem to have done much child care for their kids in the early years. Whenever he's mentioned swimming with his dad or going off to the cinema, just the two of them, some friends have said their dad's never done it. Which is a shame as having kids is a privilege (hard work but a privilege) and caring for them is precious.
