DO - make your own popsicles. They are great for a teething baby. The cold helps numbs their sore gums and it also ensures they get some fluids. Some babies drool a lot while teething so this is a fun way to replace those lost fluids. I bought a popsicle mould back in Jakarta and I make fruit juice popsicles for Connor. Or Milo popsicles for a treat.
DON'T - breastfeed just after your wee lad's just had a popsicle... it's BLOODY COLD inside his mouth then... EEEEEEEEEEEEEEEEK!!!!!
