Josh's new toy

We just got Josh an exersaucer and he loves it. It's fun to watch him learn new tricks and see him develop and grow. Josh is 16 weeks old. He finally loves tummy time! I was wondering if that day would ever come. But he just all of a sudden went from hating it and refusing to hold himself up to loving it and holding himself up great. So maybe he'll roll over soon. He is getting pretty good at grabbing things. He grabs anything he can reach and chews on it. He has recently learned how to yell (happily) so now he tries different things with his voice and strains to see how loud he can be. It's really funny. He looks at things more closely and for longer period of time. His teething pain seems more off and on now. He has been really good this past week. He only had a few bad days here and there. He still chews on his fingers non-stop but maybe he can handle the pain better because he has been happier lately.
