'rig' to hold baby "over the shoulder"

at night the only position which keeps my baby happy is 'over the
shoulder' burping position.but i have to keep her there for *hours*
till she (6kg) finally dozes off.

i hope this doesnt sound silly but have you ever seen a product out
there best described as a chair for a baby, molded in the form of an
adult chest & shoulder which allows baby to stay in 'over the shoulder
position' ? i could prop it up in bed beside me.
where could i look for something like this? i am so desperate i am
thinking of trying to sew a stuffed up one but i dont know how to sew.
thx
