DD is 18mo and naps have always been a stress. She's never settled easily for them, and still wants to BF before her nap (after which she will go in her cot asleep). She's not that interested in her nap anymore, preferring instead to stay up playing with her brother. She does get cranky at bath and bedtime as a result, and is flat out a couple of minutes after going in the cot, but we're getting to the stage where we'd rather push through this and just let her drop the naps. DS has always had to fend for himself (watch TV) whilst it takes me 15 mins to settle her, and I'd rather just have quiet time with them together after lunch instead.
She still wakes up at night, - we've never found more day sleep has helped the night sleep - the reverse in fact, her night sleep has been better after she's skipped her nap. Just interested to hear from any others if your DCs have dropped their naps early??? - I seem to be surrounded by people who say their LOs sleep for 90mins or so after lunch whilst they have a rest/catch up on jobs etc.
