Are there any good lamaze/birthing classes in Metro-Manila?

Pinay Doulas Collective offers gentle birthing classes that are very much helpful for preggers. If I had known that group before I gave birth, I would have availed joined of their classes. They have an impending workshop this June, titled "Gentle Birthing, Gentle Parenting." You can check their page for more info. Just search Pinay Doulas Collective :)
