We did. I took 7 months and then used up my annual leave to take another six weeks when DH was at home as well (which I think was really helpful). DS is now 3 and we're expecting another baby in about 5 weeks, and doing the same this time, although it's a bit different as we both work four days now, and we're both currently working from home.
It was partly practical (I earn more) and partly that we agreed we both wanted time with DS, and we generally try and split things as evenly as possible. We both know the advantages and disadvantages of being at work and at home, and I'd say we're both pretty good at being aware of that in terms of expectations, giving each other breaks etc. Personally I liked going back to work (I generally enjoy my job) and coming home to a baby who was really happy to see me. I still felt like I had time to play with DS every day, and have some lovely memories of him at that age. We both had to figure out our own ways of doing things and I feel like DS has good, if different, relationships with both of us.
Obviously I don't know what it would have been like if we hadn't done it, but generally I feel like it worked for us. A couple of practical things to think about:
a) Feeding. We were both quite worried as DS was breastfed and always refused bottles and while he was eating solid food at that stage, we thought it might not be enough. On my first day back we all met in the park for lunch just in case, but DS was happy without a feed, and was fine with feeding in the morning and evening, and having solid food/water during the day. I initially expressed for comfort during the day, but my body adjusted quite quickly.
b) Sleep. DS didn't sleep through until I chose to stop feeding at night at about 13 months (really should have stopped earlier!). He generally only woke up once but it definitely felt like I worked better once I wasn't having regularly disturbed sleep.
The only annoying thing is that DH's company has better terms and conditions for maternity leave than where I work, but he didn't get those as a father - we both got the terms of my work (which meant most of his leave was unpaid). Definitely think there should be better conditions for SPL.
Good luck OP!
