FTM needs some advice please !!

hello all, i became a first time mom in nov of 2018, when my son was born he has acid reflux which was very hard and scary to deal with because i was so paranoid were i wouldent sleep cause i s scared he'll spit up & i wouldent hear him, & when i say spit up i mean A LOt, it's getting better now that he's 3 months old but i just can't seem to get him to take a nap or two during the day, he just wants to stay up, it's like if he sleeps i'm partying without him 🤷🏻‍♀️🤦🏻‍♀️ so by the time 6-7pm comes he wants to sleep but wakes up at 10 dosent sleep til 1-2 wakes up again at 5am i'm just like what am i doing wrong, everyone keeps telling me to put him on a routine b i don't even no how or what times to do this routine to at least get him to sleep during the night , i do feed 5-6oz before i put him down, any kind of advice helps a whole lot, if you had your baby on a routine i would love to hear how to did it and wat times they would be up or asleep! anything helps! thank you
