Need advice :( new mama here

Victoria • My first baby was born 12.12.17 💙 Roman Anthony

And my sweet boy is jaundice! He’s been under the light for 12 hours, hoping his level would improve and instead of going down it went up a point and a half! Why?! What else do I need to be doing ?

ALSO- were having trouble feeding. From boob to bottle it doesn’t matter, he doesn’t suck! He will either fall asleep no matter how I try to stimulate him or he will cry!

Please help y’all :/

BTW he’s almost 2 days old
