Of course you're not being a terrible mummy!

There are some times in life where baby just needs to wait a little. Fair enough if you were still an hour away from home, I think it would be reasonable to pull over and give your bub a feed, but she certainly isn't going to suffer by waiting an extra 10 minutes or so for her feed/sleep.

Babies have a way of making us feel so guilty don't they? If you are meeting her needs throughout the day (which you are!), then she will be just fine. Once she's home and had a feed she'll have forgotten all about having to wait
