If you really want to do it you find a way.
I have excellent support in family and the back up of friends if need be and wouldn't be able to manage if I didn't. And I have just realised that my MIL who is my 'I can generally have the kids anytime' babysitter will be away one of the two weeks when I can choose my first placement and if I choose the other week my DH will be on nightshift so I am going to have a bit of juggling to do.
One of the girls doing straight nursing at my uni has a 4 month old and 2 other kids. We just had lectures today and she couldn't find anyone to have her bub for the couple of hours so she just brang her to uni. You manage!!
Good luck with making the decision. You can always apply anyway and if you get in and find next year isn't the right time just defer for a year.
