foxy, you are not a bad mummy; just a mummy who needs a bit of a break and some time without DCs around your ankles. We did the go in at 3mins, then 5mins, then 10mins and so on with DD. First night it took 40mins to settle her, second night 25 mins, third night about 8 mins and next night she just lay down and closed her eyes. DH did all the shush/patting though as I would've bailed and picked her up for a cuddle.
Now she generally goes down OK, or has a bit of a bleat and then settles. Daytime naps are a whole other deal unfortunately
bumper, that's great about DD. She was obviously saving it all up!
