hope things are getting better for you. The only advice I've got is to maybe once she's had both sides and she's still fussing for more, just put her back to the first side. I did this often with DD, especially around those fussy times and she would often have both sides twice. Also, try a good sling during the day to see if that helps settle bub. DS has trouble bringing up his wind, and I find if I lie hime down, he wakes up about 15-30mins later in pain because of the wind, so when he's asleep or settling down for a sleep, I'll pop him in the sling (i have a hug a bub, which holds him upright), he may have a bit of a windy cry for a few minutes, but then will generally do a big burp (and normally chucks up straight down my cleaveage and then all of a sudden, he's asleep and has a much better sleep in that than in the pram/bassinet etc.
