hi Zyp,
heard that the Lampe Berger is good... been meaning to get one, but quite ex, although hubby has membership card with them.
Btw, is your son still phlegmy? My boy had a cough problem for the longest time. He even developed bronchiolitis one time and had to be hospitalised. He also needed to be nebulised frequently. We had no choice then but to invest in a nebuliser for him.
But once he passed 18 months, his condition improved. Also, my colleague advised me to reduce the formula milk strength for him. Since then, it has worked wonders!
