Well i am a father not a mother

our kids are 3 and 11 months. My wife is deffinately the primary carer as i have a job and she is a housewife. However when i am home i give my fair share looking after the kids. Bathing and playing and generally looking after them is not a chore as it is valuable time with my kids, which i would not give up. Plus i bet your work looking after the kids and house is harder than his(if your kids are anything as boisterous as ours

). He should deffinately have some time himself looking after the kids so he can spend quality time with his children and you can get your sanity back. If he doesn't he will regret the missed oppertunity in the future. well thats what i think anyway.
