If the baby breastfeeds with a good deep latch, and has strong enough tongue function to press the breast against the palate, the palate shape can change quickly, in as little as a week in a young baby. Most reflexes don't really "disappear", they get outgrown as they are incorporated into voluntary movement patterns that they often form the basis of. If reflexes are not becoming volitional, this could possibly signal that the baby's neuromotor development is delayed. I'm sure the OT's and PT's on the list can explain this better than I can, I have just a rudimentary understanding of the issue. -- Catherine Watson Genna, IBCLC New York City mailto:[log in to unmask] *********************************************** The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(TM) mailer for lightning fast mail delivery.
