Charlie will be 14 months when we go on holiday, hes in 9-12 now but most of them are a little big for him so i have a few questions..... 1] What size to ge him, 12-18? or will he still be in 9-12 then?? 2] Do i get him little t-shirts so his sholders are coverd up, or do i get him little vests so hes nice and cool and just put extra sun cream on his sholders? 3] Will he be ok swimming in his little shorts or will he need his back and his tummy covering?? 4] If i go with little vests ware on earth do i get them from!? All of your help will be greatley appriciated!
