I am a SAHM, with a baby and a 4 year old. Been on lots of walks lately with friends who are also mums at home with babies or kids at school. Nearly all of them get a phone call from there partners while they are at work, just to say hello and see how things are going. My partner doesn't do this and when I told him all my friends get calls he said it is weird.
Does your partner/ DH/DW call you?
