dear all mummies, I'm a new mum with 8 months old baby boy. And I have no idea why my baby's skin appear reddish even in the aircon room. and it seems like he like to scratch his skin as well. i bring him to the doc and she was actually told me to keep my house environment clean and dust mites free cause his skin is thin and sensitive. dust mites free? gosh anyone knows how can i make my house dust mites free? is it spray febrez can help?
