Interesting point about making changes during a developmental transition. As the world is presumably going crazy for him at the moment, one more thing may not make so much different. I'm so looking forward to this growth spurt being over nonetheless as he's been so randomly cranky - think we're almost there. He has been extra ravenous this last week, and he's 19 weeks Tuesday and has been fairly punctual with growth spurts so far.

I'm pretty sure he's started sometimes crying/grizzling with frustration recently when e.g. he tries to roll but can't remember exactly how or can't reach things he wants to reach. Feel like I should let him experience a little bit of frustration and finally succeeding though.

Making slow progress with the sleep I think. We have had two naps without a blindfold now and I now think of a 3 hour longest stretch at night as bad rather than great!
