can any mums help me out? I'm due back at work April 2017. I'm thinking about going back on two maybe 3 days as family and my partner can have the baby for me. if I was to go back on 3 days it'd be 21 hours and 2 days it'd be about 14. I know I'm entitled to child benefit but would I be entitled to any other help with my partner working full time? thanks x
