My 3 month old developed 'reflux' at 2 weeks. She didn't throw up loads so I thought it may just be over-feeding but she was so fidgety on her feeds and couldn't relax at all. GP said it could be mild reflux and prescribed Gavison. Seems to work but now 3 months on she still needs it - will this problem go away on it's own or is it a long-term thing?
