Yep I'm one of nickel's friends & both Matilda & Jovie have the wheezing after a feed. If it gets bad it must be checked as sometimes when they reflux they breath it in & it aspirates in their lungs. Different things helped Matilda, which don't help Jovie so its hard to say what works for one child... but for Matilda the HA AR thickened formula (NAN) was the best.
