2wk old slept for 5hours

HALEY • @bedtime my kids turn in to dehydrated philosophers who need a hug. 😍😘
Our pedi said to let our little sleep through until she wakes up for a feed, since she was gaining weight. 
Last night she slept for 5hours straight woke up for a feed and diaper change and then slept for another 3 hours. She is sleeping a lot ... Normal? 
Since this morning I have only fed her 2x and she is back to sleep.
