I think what is best for Chelsea and yourself is the best, if you feel more comfortable leaving her with a friend that would be your best decision.
Yes you do get help by the gov with Childcare fee's but this depends on how much you earn. Example- I have Madison in one day a week and i pay $16.30 for the whole day and my friend has her DD in the same centre on the same day and she pays just over $44 for the day.
If I was you I would leave her with your friend
