FJ Its very very hard, and yes we all go through the roller coaster.... with M school holidays is very hard, and always the added issue of anticipation is bad. Whenever some holiday that she loves, or a party or anything will encounter a meltdown. Mainly because her stress levels increase from anticipation, but in reaction to this, she can't handle changes to routine or changes in anything.... so school holidays, public holidays, changes, sugar.... etc etc etc... make life horrible. She had 3 meltdowns today. 3. I can't imagine going through that with a newborn...

I imagine that Evan is very frustrated and confused with life. Maybe each morning if you give him an ideal routine, and make sure you say that it does all revolve around needs of the entire family.... then remind him what is happening next? Also, if he starts feeling stressed, or you see him getting frustrated, you can always do some OT things...

Core work calms. Breathing calms. Make him blow up balloons, or do wheelbarrows, or sit ups, or squash him between two large cushions. Something to make him work that core and in turn help him calm down. I would do those things even when he isn't worked up, in order to help him calm down, put the fire out before the storm.
