nap problem

my twins always catsleep during the day. konting ingay or natanggal lang pacifier sa bibig nila gising agad. weve tried everything. white noise, feeding before sleep, rocking them, higa sa duyan everything! but they always wake 5-10 mins of sleeping. eto na routine ko maghapon eh salitan pa man din sila, sa bedtime at night nalang sila nakakatulog ng mahimbing. HELP PLEASE
