Hui - Indeed not many clothes to buy for BB boys. It's either shirts or shorts or pants...
Anyway I have asked the supplier to source for cute cute BB Boy clothings. Will let you all know if got any lobang.
Agree with Serrich tat no best sizes to buy coz a lot depends on cutting. I personally prefer to buy separate tops and pants for newborned baby coz sometimes after drinking, they vomit out some milk so if wear full-length rompus, gotta change entire piece but for separate pieces, I just change the top. Same point if the urine leak so need to change bottom only.
I buy about 6 sets of newborned longsleeved tops and pants for nightwear (in case rain and clothes not dry and also baby may vomit milk, leak urine, etc). For daywear at home, I also bought 6-8 sets of shortsleeved and shorts for newborned (My baby sleeps in the hall during the day and for S'pore weather, most times no need too thick or let baby wrap up in longsleeved tops/pants). Better to get button-type when they are 0-3months, easier for mommies to handle when their necks are still very soft. I got about 6-8 sets of mittens and bootees coz my baby sleeps in aircon room at night and also, for hygiene sake, change often (especially if they put their fists in their mouth). These are only for home wear. As for going out clothes, can buy an assortment but don't buy too many for below 6 months coz they grow very fast during teh 1st 6 months.
Hope that helps
At the end of the day, it's the mommies' preference
