Just received this e-mail from bambino customer support.
Hello name removed, yes we have receive your e-mails and with the help of your photographs have discussed the problem with the manufacture who just returned from their Chinese New Years vacation.
The higher placement of the tape tabs on the medium Bellissimo was due to the increased overall length of the diaper . The manufacture felt the need to raise the tape tabs up by 1". The gap between the tape tabs has remained the same. This change in this manufacturing run may cause some people to have to re-adjust the diaper to fit more comfortably. We will be evaluating the need to lower tape tab positioning on the next manufacturing run.
Regarding the padding, the core was reduced by 1" while the plastic was increased by 2". However the weight of the core and the core spec has not changed.
The leg lycra gathers (stitching) on the photograph you sent us is out of spec and could effect the seal around your leg, there should be at least 3-4 strands of lycra for it to be in spec.
The overall spec of the diaper in terms of core weight, amount of SAP and total absorbent capacity has not changed.
name removed, we stand behind our products 100% and will either replace or issue a refund for those diapers that are missing the correct amount of the lycra strands. Please let us know how many diapers are effected and how you would like to proceed.
