Am going to Majorca in July with 7yr old DS and 8mth DD. Have never been abroad with a babe before and wanted some advice. Is it better to have swim nappies (and possibly get through 4 or 5 a day) which are a bit expensive over two weeks or a swimsuit with strong elastic and probably have to wash it out 2 or 3 times a day? Also as DD will still be having bottles can I use bottled mineral water to make up feeds (wouldn't be confident about tap water) or are there too many chemicals in it, in which case should I just resort to full cream cows milk for the fortnight? Any advice would be very much appreciated!
