Reflux/backflow Of Milk

Hello po. My LO is 1 month. Lagi po lumalabas sa ilong nya ang milk. Kahit nkakailang burp nxa after feeding at more than 1hr na. Pag pinahiga, bumabalik ang gatas. Minsan in the form of lungad but most of the time sa ilong. Sabi ni pedia ipaburp lng dw and iwasan na ma overfeed. Mixed feeding po xa. Every 3hrs si formula milk followed by breastmilk. Pag gutom ulit after an hour, breastmilk nlng. Super takaw po talaga. Any tips po na maiwasan na lumabas ung milk sa ilong nya? Super iyak po xa everytime.
