my 8 month old takes a couple naps during the day and he was used to his great gran holding him to no end when he was tiny and she thought his naps should be couple hours but now he is older if you hold him he will sleep longer but a 30-45 min nap is normal for him he needs less sleep during the day and more activity and play time she actually told me she thought he was sick becuase he wasnt sleeping like he used to he was bored at times and got cranky but if he got more play time he was more tired and nap for almost an hour and was ready to play again he now takes his naps in his play pen and sometimes he wakes up happy sometimes not if he eats right before nap time he wakes up happier if he falls asleep and hasnt had a bottle or baby food within a couple hours he wakes up screaming cuz he hungry again dont know if this helped or not but maybe he has it a groweth spurt and needs smaller naps instead of the longer ones. My little girl never and I MEAN NEVER napped more than 30-45 minutes at a time even when she was 3 months old so every bay is different i know and they all grow so fast some babies like smaller naps than others my lil boy takes a longer nap in the a.m. with me cuz we curl up together after my 8 yr old goes to school but i work weird hours and the late morning is mom and baby nap time together LOL then he only takes 30-45 naps during the day with my mom

. he might take 3 naps some days 2 on others. and they are spaced out from 9 am to 6 pm i dont get home til 8 pm or later and most night he is fighting sleep to see me it seems anyways hope i helped
