hello, i am british, dh is dutch and we do opol with our 12week baby. Ive always thought he might be a little late in speaking later on, partly because of bilingualism, partly because dh and lots of his family were very late in speaking (but got there eventually). There are baby signing classes in my area and i was wondering if anyone had found them useful, especially with bilingual kids? Or does it muddy the waters more?
