DD is 4 and a half months old (3 and a half adjusted). We have a pretty good night routine sorted - she sleeps 7-7/8 with wakes for feeds around 2 and 5.
However day time naps are random and generally only short. Some days she'll have a 20 minute nap then be up for an hour then another 20 minute nap and repeat all day. Other days she'll manage longer naps (40 minutes) and be up for slightly longer.
She feeds to sleep at night but not every time during the day. I can spend an hour from her showing signs of tiredness (yawning and rubbing eyes) before she'll go to sleep. Then she'll wake after 20 minutes and i'll try to get her back to sleep but she just wakes up more!
At home I'll take her to the nursery, close blackout blimd and have all lights off except night light and rock with her in rocking chair till she's asleep then put her in cot. Same as at night. When out she just won't nap and gets herself worked up and over tired, but that's a whole other problem!
How do I get her to nap longer and less often?
