There have been a few posts on here recently from people expecting their second dc and worrying about how they'll cope. I have two and very low standards of cleaning etc - my house is scummy, and the children and I often wear slightly grubby clothes.
If you're like me I don't know if this will inspire you, comfort you or just make sure you reach for your contraception next time you and your dp get friendly (how do they even find the time and energy?)!!
