oh poor you, it's so hard when you can't find out why your tiny one is crying! it will get better as you get to know your baby and get more confident and experienced. (having said that, i'm currently mning to stay awake with ds2 in my arms in the armchair< dreading lying him down in case he starts screaming again! (hence crap one-handed typing)
here comes self indulgent blah but please bear with me, hope you can glean some wisdom from my similar tale of woe!
my ds2 is 4weeks and tonight was the first evening he has cried for ages. he's been much more alert the past couple of days, really lovely, even got most of a smile today, but i'm sure he's a bit overtired and that's contributing to his distress. he's been on and off the boob all evening but didn't settle, culminating in massive puke around 11pm. he carried on crying for a good hour after that and nothing seemed to help.
then, thank god, i remembered my trusty old sling. popped him in and marched round the house for a few mins, he went straight off to sleep. bob's your uncle. this always worked with ds1, we've used the sling with ds2 but mostly just to get hands free for playing with ds1, ds2 is normally such a peaceful chap!
i find a wrap sling works best for getting to sleep and also seems to do wonders for getting wind out - both my dss often do/did a great big burp after being popped in. we have a kari me but there are several different brands (didymos and close spring to mind) cost around £35 i think but you can get one cheaper on ebay.
as for putting down, i'm no expert on this as we didn't really put ds1 down for the first 4 months or so. he was quite a needy baby so we decided just to keep him with us - dh would take him for a walk in the sling while i made dinner, we'd eat with him in the sling and then watch telly, but switch it off if ds1 was restless. this got impractical when ds1 got older and needed more quiet and a routine to get to sleep.
this time round i'm trying to put ds2 down for at least one of his naps each day so he gets used to it and i can spend one to one time with ds1. being an obliging second child he seems coolwith this but has struggled to lie flat on his back lately due to a cold. (hence mning at silly oclock!) i've put a folded blanket under top end of his basket and lie him slightly on one side - safer than lying on front, prob not quite as safe as ob his back but as he's in the same room as us i feel comfortable with side sleeping position.
at night we co sleep, overall this has bought us many many nights of lovely sleep but has been tricky while we both have colds - i need to be propped up but don't think it's safe to have ds near pillows, and ds can't feed lying down without puking. mumsnet has become my nocturnal friend!
op, can i suggest you repeat your post in the sleep section? you might get more responses, especially from soppy hippy types experienced baby wearers and co sleepers like me! also you might like to check out which has lots of info on sleep.
good luck to you! hope you and dc are fast asleep and don@t read this until 8am at the earliest!
