I wish my LO would only have 1 hour long screaming sessions! You are lucky imo!!
I took Logan for a weekend trip to visit grandparents and he screamed upon arrival, the entire next day (took one day break from screaming), and then today our first day home he screamed all morning.
All I can say is THANK HEAVENS for babywearing its the only thing that will calm him down today.
Oh and to respond to the boob preference..... been there done that. My LO goes through it often and if you just keep offering the 'bad boob' they will eventually take it. Sucks for feeling lopsided though.
