Feeding schedule

Kaylin

I have a 6 week old and she currently eats about every three to four hours during the day. About 1.5 weeks ago, she stopped waking up every 3-4 hours at night to eat. I have been waking her up to feed. Is that wrong? Do I let her sleep until she wakes up to feed or should I continue as I have been? She has gained weight and her pediatrician is very happy with how she is doing.
