It was hangry-ness that caused problems- for the grown-ups, too! The first couple of days I was so focused on sticking to The Plan and not missing any of The Things We Had Scheduled and forgot to take breaks for snacks (if it wasn't an ADR, I had forgotten to really factor in meal time). As soon as I found myself snapping at Hubby, we realized- crap, we need something to eat. We always made sure the 4 year old ate a breakfast-y thing in the room while we were getting ready, but the two of us figured we'd grab breakfast in the park...but then we'd run from attraction to attraction. The only near-tantrum out of the 4 year old happened mid-day at DS (ironically our day off) because we hadn't really had lunch and were having a late (for her) dinner, so we immediately found ourselves a couple of nice big pretzels to split and we all felt better. By about day 4 of the 10-day trip, we figured out a schedule that worked best- for days with no breakfast ADR, snack in the room, rope drop whatever attraction we wanted to rope drop, and then hit the in-park Starbucks before heading to our first morning fast pass. Coffee + breakfast item = happy mom; happy mom = happy family. Midday snacks + in-stroller nap = content 4 year old who can hear the word "no" without freaking out = happy mom = happy family.
