First you are doing a great job!!

If your bub doesn't want to sleep anymore she will soon let you know.
Babies have a 2 4 and 6 week growth spurt so it's normal to do heaps of eating and sleeping

I'm not a big chatty person either, but as your bub shows more signs of not wanting to sleep all the time and you have to start occupying her more you will soon get the hang of it.

Remember you have only been a mum for the same amount of time she has been a baby. You are both learning together.
