Tapping the expertise of the Family Room! Twosling (10 weeks) has started having a regular bottle of formula each evening as a top-up to his feed. He sometimes doesn't want any, but generally takes 1-3oz of the 4oz he's offered. He's also had a couple of bouts of windiness and green, 'upset tummy' poos in the same period, the last 2-3 weeks. Might be co-incidence, and HV didn't think there was any connection, but wondered if anyone had heard of formula, or particular brands, causing wind? Many thanks! Moos
