Hi bro, I personally prefer SM Makati, Glorietta, and SM Megamall :) Try waiting for the SM 3-day sale which happens every few months, usually during the 2nd and last week of the month because this is when most people get their salaries. So malls take advantage of this. :)
Try heading to Shangrila Mall in Edsa. There are a lot of baby stores you can shop from.
