Gill Rapley's response to the study you note:
"The study used data from the Gateshead Millenium Study, and the lead author is Charlotte Wright - all excellent credentials. In a nutshell, the authors found that, based on when babies began to reach out for food and feed themselves, BLW is "probably feasible for a majority of infants". There is a caveat that it could lead to nutritional problems for infants who are relatively developmentally delayed - but then again, no-one has ever claimed otherwise.
The GMS data show when the babies began reaching out for food and feeding themselves, and how many finger foods they were having (type and frequency) at six and eight months. The authors acknowledge that these babies were born (June 1999-May 2000) before either the six months recommendation or BLW had come into being, and that the parents' reports may therefore represent low parental expectations of their infants' self-feeding capacity, rather than genuine lack of ability. In other words, if they'd given them the opportunity earlier, who knows? So the fact that, on the basis of the data they do have, they are able to conclude that BLW is "probably feasible" for the majority is just great!"
OP - if you feel more comfortable with weaning your baby traditionally then do, but if you really want to have a bash at BLW I'd just start when your child is showing signs of being ready, prem or not :)
