Breastfeeding Momma

Exclusive Breastfeeding kami ni baby since 2 days old siya until now. Nag-formula lang kami on his first day kasi wala pa talaga lumalabas na milk sakin. Now, 1 year and 3 weeks old na si baby. Parang humina na milk supply ko. Plan ko pa naman sana mag-breastfeed ng longee kasi G6PDD si baby and di ako panatag bigyan siya ng formula milk as supplementary kasi most formulas has soya. Is there a way po ba para magpalakas uli ng milk supply? Malakas po ako magsabaw and water. Nagmimilk din ako, milo, and M2.
