not sure if this has happened to anyone before, but my baby was on a pretty good nap/sleep schedule (we use marc weissbluth's healthy sleep habits, happy child) BEFORE we came back to canada. now back for 2 weeks, her nap/sleep is a nightmare. i think she's over the jet lag already. tried letting her CIO & a few days ago & she vomited as a result... this happened again yesterday & today. it seems that she knows that vomiting would get our attention right away (and given the mess, it's not something we could ignore) anyone with similar experience, pls share & any advice apprec!!!
