Baby water in bottle

Ung water ba ni baby nag iiba lasa at the end of the day? Everytime kasi na huhugasan ko na tapos pag may naiiwan na water iinomin ko para hindi sayang, eh iba na lasa. Wilkins water nya. refill sa umaga tas at the end of the day huhugasan na. Like ganun ba talaga? Pang water lng nmn nya ung bottle nya kasi exclusive breastfeeding baby ko. Nahuhugasan at sanitize naman everyday
