Hypoallergenic Formula milk

Hello. Ask lang ako what HA (hypoallergenic) formula milk yung gamit ng baby nyo. Hindi kami makapag breastmilk kasi hirap sha mag latch sakin. He had diff latching since birth since he had infx so we resulted cup feeding muna kaya lang parang na nipple confuse na sha kais mas pref nia cup kesa actual nipple ko since mas marami shang nakukuhang milk so we were given a go signal to use formula na ni Pedia. Similac sana kaya lang wala akong makitang HA variant nia. Hindi rin naka indicate na HA yung regular at nag iisang variant nia for 0-6mos sa stores. Nan and S26 lang yung nakita kong may HA. #pleasehelp #firstbaby #firstmom #advicepls
