I haven't had time to read all the replies but in our home, DH parents as much as I do. He works 6-5 Mon-Sat and when he leaves his job his job as Daddy/Husband kicks in. He will usually pick up some stuff from the shops for me. When he comes home he plays with the kids, or reads to them or watches a DVD whilst I prep for dinner (peeling, chopping etc). During this time he will change nappies if needed. He then comes and helps me cook dinner whilst DD1 puts the kids in the shower or he will bath the kids whilst DD1 helps me. When I put the kids to bed and read them a book, DH is usually doing a clean up of the living areas - putting toys away, wiping things down, quick vacuum etc. THEN, we get some time together to lounge around and chat. Some days, he will be the one putting the kids to bed and I will do the clean up, or he will cook and I will bath the kids etc.
On his days off, he pretty much always lets me sleep in because his body clock is set to getting up early. If I wake before the kids, I will let him have a sleep in.
DH helps with the cleaning on weekends, which is usually our do-a-massive-clean time in preparation for the week. He will help with pretty much whatever I ask him to help with. He knows I am here looking after our children so he can have the best of both worlds - a large family & a job. Anything we can do to make each others lives easier, we will do. We are a great team and that is what makes us work as both a couple and as a family
