Here's an idea, on one of those mornings per week when you have sole care of your daughter make a point of discovering parks, gardens, playground equipment, open spaces, places of interest, etc around your area (I did a quick google of Penrith and it looks as of there are plenty of places around) even if only close enough to be within your time contraints regarding work or other commitments. Somewhere that your daughter can run off some energy or have some focus by getting her to find you a pretty flower, small bird something she likes that you can photograph. I don't know much about children of that age group but photographing stuff found during mum and daughter time can have dual purpose of getting you to take a photo of a bridge, a bird, a weed, a swing in the breeze, a distant mountain etc etc plus have a record of that time you spend together. Anyway something to get you thinking.
