Aw congrats sa bebe! Hehe honestly I started around 5-6 months pa lang kasi nakakacute talaga, pero a few of us mums agree na wag masyado marami because babies grow SO fast, nakita ko yung newborn stuff ng kaibigan ko na hindi na-suot, sayang! I'd say start with basics lang (onesies, sleepers, mittens) around 6-7 months, then add cute pieces gradually closer to due date, plus ask your family din kasi marami talaga ang magbibigay hehe.
