Bit of background: I'm German by birth but have grown up in English-speaking countries and feel entirely English in terms of my identity. DH is English, we live in the UK.
I've got 2 DDs aged 1 and 2, and I've spoken to them almost entirely in English for most of their lives. I know I'm a wimp (please be gentle with me on this count as I do feel quite guilty), but I just didn't have the strength for OPOL as I would have had to be the minority language parent and it does feel like an effort speaking German these days. I'm fluent but just don't quite feel like "me" in German, if that makes any sense...?
DDs are exposed to German through lots of songs, stories and very frequent grandparental visits but I'm starting to feel like I want to do more.
Has anyone else introduced a new language to DCs at the age of 1 or 2? DD1 talks very fluently and DD2 has somewhere around 50-100 words. I don't want to confuse or upset them and I don't want to recreate the battle of my own childhood home where we were constantly admonished to talk in German. I've read a lot about the effort needed to make bilingualism work and, whilst I'm happy to put in some work to give my DDs the gift of another language, I don't want it to make us all miserable.
Thanks for any tips!
