not nursing often

My breastfed baby is 6th months old, he's eating na once or twice a day pero 1-2 teaspoon plang nauubos nya... normal lang ba na madalang nlng cya mg milk, pag magmimilk cya minsan sobrang bilis like 2-3 minutes aayaw na cya.... minsan buong morning di sya mag mimilk try ku sya pa dede pero ayaw nya... sa pampers nya my orangey na pinkish.. na search ko, dehydrated pag ganun.. siguro dahil di cya ng mimilk often kaya ganun?
