Hi,
Welcome to Bw-site! You will find us to be a very helpful and fun community! But, you may also find us to be a bit addictive!
I'll start by asking you to post your routine so far....then we all have more info to help you with.
In my experience, a 10-30 minute nap is caused by overtiredness. Your baby, for her age, seems rather overtired and should be napping more. (you know this already though)
We can fix this...but we will also need to know if you have ANY nap routine (winddown etc). Same for bedtime...what are the things you are doing to signal to your lo that it is time to sleep???
Hope to hear from you soon!
