Noah has started to chew on stuff (his hands, the bottle, etc), so I suspect he may be ready for teething-type toys. He's still too little to manipulate bulky toys, though. I may have found the perfect solution in a baby toothbrush. It's small and light and easy for him to hold on to.
And apparently delightful to chew. He spent a good part of the afternoon working on it.
Noah's drooling has also started to get out of control, so today we tried keeping a bib on him, thinking this would also help with spit-up mitigation. Here you can see how effective that was.
I do think Chad escaped unscathed, though...
