At around that stage Dh and I didn't get on well. I truly think men can't understand what it is like to have your body invaded by pregnancy, then scarred by childbirth, then drained by breastfeeding and a new, unpaid 24.7 job with sleep deprivation thrown in. their lives don't change in anything like the same way - their bodies haven't been harrowed and they are sold the myth that motherhood is this sweet smiling glow that comes naturally to all women.
For us, the breakthrough was to structure our weekends into 4 hour chunks of time: Friday night, Saturday morning, afternoon, evening. Same on Sunday. That's 7 good blocks of time in total.
Every weekend we'd each get a four hour chunk on our own, to do whatever we wanted, wherever we wanted, and the other one would look after the children. If it's a lie-in, the other one takes DC out or entertains them so they don't pester. We'd have a chunk of time where we went out ourselves and got a sitter in. A chunk where one minded the children and the other did chores, and then vice versa. (That stops men from thinking you can simultaneously entertain a baby while cleaning, cooking and shopping as effectively as before.) And two chunks of time when we did something nice as a family - either a whole day out or two half days. Obviously that leaves 8 hours for 'sleep' - take turns having an unbroken night, and another 4 hours each day to eat and shower and faff.
If you do this every single weekend for a few weeks, you settle into a rhythm where both adults feel their needs are met and respected; where jobs get done and - best of all - great fun is had as a family and a date is squeezed in each week.
Final tip, we learned from experience - don;t pay a babysitter then go out for a drink or dinner, You just end up glaze-eyed with nothing to talk about except your child or your relationship issues. Have dates that give you new, fun common ground and stuff to talk about. Go to comedy clubs, theatre, films, gigs, concerts, ice skating, rollerblading - whatever you truly love doing.
