Pediatric Books/online studying for new peds nurse?



I am a new pediatric telephone advise nurse. I have been working for 4 months. It has been going well so far but sometimes I feel like I know nothing! I use the pediatric phone triage book which is helpful, but I was wondering if anyone has recommendations for good books or websites to study? Things I struggle with are giving parents advice on how to help with behaviors, breastfeeding/formula, newborn stuff in general/what is normal. Any ideas? A lot of stuff I have not learned in nursing school. Again, the triage book is helpful but sometimes it doesnt have answers to parents questions and I am not always sure what to say and I want to be more prepared! Thank you!
