Yippee! I m not the only sotong one (heehee sorry, me bad, but I feel so dumb sometimes)
Apparently, pram is for newborns to a few mths old coz they cannot sit up & they need to lie in the pram. Stroller is for older BBs/kids when they can sit up.
As for what's the diff in terms of weight, sturdiness, pricing, .. I dunno liao.
Maybe one of the more knowledgable mummies can enlighten heehee?
