Baby stuff...

Hi I am a first time mum, sobrang confused ako on what and when to buy stuff for my baby any suggestions? My fiance told me to buy the important ones like baby bottles. Though pagdating naman sa baby bottles i got confused with dr. Browns or avent. Ang dami dami kung gustong bilhin. Kaso pag tinanong na ng fiance ko if needed ba talaga ni baby wala naman ako masagot kasi nalilito ako. ? hope you guys can help me input ideas.
