DD has a Miffy figure that she absolutely adores. It is very rare (was mine when I was a child) and thus, irreplaceable. Consequently, I never let DD take it out of the house. This has never been an issue. She plays with it constantly in the house and when it's time to go out I remove Miffy then distract her.
DH (who knows that Miffy is rare and how important it is to DD) let her take Miffy out with the inlaws for the day - and they fucking lost Miffy. FFS I am fuming and feel quite upset. Now DH is all: "You're overreacting and spoiling the weekend". Fuck him. He's not the one who has to deal with the consequences of this 24/7, I however (as a SAHM) will have to deal with the tantrums and crying.
