Hi we have a couple of tommee tippee pelican bibs for my 9 month old but the bib seems to be too wide for him - he can only use one arm properly at a time as the bib pushes slightly to one side by the arm he's using and the other gets 'trapped' behind the other side side. To save us buying a million different brands, can any one recommend a slimmer pelican bib that may solve the problem? (We've got long sleeved bibs too but prefer the pelican ones sometimes)
