do schedule this!
The very next action is to determine in consultation with your child's mum, what times work for what kind of play (quiet, active, arts and crafts, park) and how these can fit in with your schedule. Part of a relationship with a child is the child knowing what to expect from whom and when to expect it, so once you pick some times, try to stick with them. Let's say you are get home from work at 7:30 pm, that might be pretty close to her bedtime, so maybe on the week nights she could have a bedtime snack of milk and a biscuit with you , then you brush her teeth while you sing a song or two, read a story and then tuck her in for the night. If you have time in the morning, some active play might be good, even if you have to get up earlier than you would usually and wake her up, 15 minutes with PaPa rolling a ball or looking for birds, or walking the dog together is something of great value.
