Same as mummyNaomi. I have 1 day WFH and I have my 18month DS with me. I generally do work when he naps(around 2 hr in the middle of the day) and then may fit some in early morning when hubs is home or in the evening when DS goes to bed. I also do a lot of extra work outside work hours (teleconferences with Europe in the evening, traveling outside standard work hours etc) so my employer is very flexible with me on my WFH day cos they know I put in the extra work when it counts and it evens out. Bit of a different situation to you though. Good luck!!
