Fav ko ipasoot cotton pang-araw2 sa 6mo boy ko dahil mainit ngayon:
Some old white "Loving couple" sleeveless sando (un pang-girl na zigzag embroydery-malalim daw kasi kilikili ng pang-boy, cotton pajamas, cotton onesies from Babyland store and sleeveless onesies from "Cotton Stuff" na from may eldest pa - super sulit and durable:)
I usually buy in Makati - parang andun na lahat: Greenbelt Mothercare, Babyland, SM, Landmark and Glorietta
so far yan lang naaalala kong brands i'll comment again kung may worth sharing sulit brands, icheck ko sa closet
