My DD is almost 6 months old & used to be a great night sleeper but has always only catnapped during the day. She is still ok at night, only wakes once for a bottle & usually goes straight back to sleep with minimal fuss (used to sleep through before the 4 month sleep regression). Her cat napping during the day has gone from 45 mins to 30 mins & she often seems to be tired mostly as the day goes on, I have tried resettling but no matter what I do she will not go back to sleep after that first 30 mins. I have tried the babybliss methods & that didnt help her at all. She self settles to sleep for her naps with only minimal grumbling most of the time, if she gets upset I either pat her to sleep or rock her but she only needs this occasionally. Does anyone have any advice on catnapping? Is there something I should be doing to help her sleep longer? Should I be worried or will she just grow out of it in time?
