Hello, we're going on our first family holiday to Mallorca next month. It is the first trip abroad with baby and I wondered if I could get advice from mums as to any health tips? She has solids and formula milk, but should I give her water too when abroad to prevent dehydration? My health visitor put me off giving her water as she said it would fill her stomach up and lessen her hunger!!! Any other advice gratefully received. Cheers
