Answer:
As a father in the early Paleolithic, life is hard, survival is not certain, but there are some upsides to it.
You wake up early, when the sunlight reaches your cave. You tell your wife to take care of the kids while you go on a hunting expedition with the other male members of the tribe. The tribe is small, it only consists of 20 people.
You hunt a few small animals with your friends: two rabbits. This takes you around 4 hours. You go back to the cave, and help the women cook a meal.
By 2 or 3 pm, you have eaten plenty, and use the rest of the time for leaisure: playing with the kids, or simply hanging out. Perhaps some of the time is used to polish a few stone tools, which are essential for hunting and survival.
