This post is actually a couple weeks old; I wrote it on Tumbler and then on the Fluent In 3 Months website forum:
I resorted to English far too often yesterday with the kids and also with hubby. It’s so frustrating when I can’t think of the word for something off the top of my head and let myself slide back into my native tongue. Hoping for a more productive day today, but it can be a challenge to maintain course. Especially if I’m bothered by something or stressed out – then I literally cannot keep myself on track. Maybe this is normal, but it’s very annoying.
