Different babies have different sensitivities.. I think wool doesn’t irritate most babies’ skin per se, but because it’s warm, baby may be prone to heat rash. Cotton is still the best material for Singapore weather:) and my little one has not used a blanket since birth.. safer for infants to not have it:)
If you’re planning to let your baby wear mittens/booties, would you consider knitting a pair of those instead?
