We took the pre-crawlers class with Micaiah when he was about 10 weeks old. It was really really excellent. I knew there were things I should be encouraging him to do, and also knew there was probably a type of way I should be encouraging him, but wanted to make sure it wasn’t stressing him out or moving him in ways that weren’t helpful (or, contrary to natural body movement).
The class is short (45 minutes) to sustain his attention (and mine), got to meet some other great moms, and it really helped build my confidence to encourage his natural movement (and know when he needed a push in a certain direction). I was actually pretty amazed by how secure it made me feel at the end in terms of where he was developmentally and where we were headed in the future.
