My DS was in hospital 2 weeks ago having ingunial hernias repaired. Because he was having a general he had a couple of NBM periods - both around 6 hours. Once he'd recovered he had a bit of a growth spurt (or maybe just catch-up)for a couple of days, and ever since he's got into a snacking routine. What's the best way of getting him back into a big feed routine whilst causing him (and me!) the least amount of distress?
