hi YuetYan,
learned from YMCA - CSW center yesterday that the group can run as scheduled. know that they have 6-7 confirmed babies (including me), so you could call them if they will have other new class or you would join the original class.
BTW, i am looking for the mums to the survey and see if you are fit & interested. Qualified mums will have HK$550 after conducting the survey.
