boris the weekend sounds like a nightmare, you should def re schedule it for another time!!
bunnygirl OBVIOUSLY you need to be spoiled on BOTH mothers days!!! simples 
re sleep and self settling i really think that although you can encourage it and help your baby to learn it, a lot of it is pot luck and down to personality/temprement. out of my 5 ds1 was a terrible sleeper and is still not great at 11yrs old, he knows better than to disturb me in the night now tho lol.
ds2 was better, then ds3 was kind of inbetween the two, then we had ds4 who was a revelation a baby that did self settle (sucked his thumb) and slept really well, BUT he has now been having issues with night waking age 3 
merryn is better than the first three boys but not as good as ds4, she has a dummy for daytime naps but generally doesnt need it at night, tho i tend to give it to her just before her 5am feed, but thats more so she doesnt shout and wake up ds4! there is def a trick with catching merryn at the right moment, tired and sleepy but not too tired and then she will settle fine for her nap, i still swaddle her as she likes it and sees it as a cue to sleep and then she goes in the pram for daytime sleeps, generally i just stroke her head a little and give her her dummy and then she goes off, sometimes have to rock the pram a bit.
she will also sleep in the sling and when we are out she will cat nap, but havent used the sling much this last week or so as i have been ill (chest infection) and had a horrible temperature so havent wanted her in the sling making me even hotter or incase i cough all over her.
sleep defintely breeds sleep tho and the more a baby has the better they seem to sleep, but merryns naps vary in length hugely, sometimes she will have a big two hour nap in the day and other days she just has short naps, it depends on what we are doing and if she is disturbed by her brothers, tho luckily she is quite good at sleeping through noise generally and she will consistently crash out by 7-7:30 for the night, waking at 11:30 for a feed and then again at about 5am, which i think is pretty good and she then sleeps in until 8ish sometimes longer :)
bunny hope will gets better soon, merryn has a cough at the moment she doesnt seem too bad tho it has affected her sleep a bit and i noticed today she is a bit warm, so have been giving her a bit of calpol and i will watch her and see how she goes, hope she doesnt get poorly like i have been, would be typical on a weekend when dp is at work!
