Shelter nurture mode - days 1 to 3

In game called Shelter there's nurture mode where you are supposed to take care of your babies everyday, they get older and more areas open for you to go as the days go by. Last time i started it i got to day 18(i think) then didn't play for a while, came back at day 44 and my babies were dead... This time i will try to play till they are old enough to go on their own ways, not sure how many days i will video but i will film some.
