Our son is about to be 7 months. Lately in the past week or so he's been really cranky and fussy while playing wheras before he could be quite content alone, even for up to 1/2 an hour playing(of course with us keeping an eye on him).
He has just started crawling around everywhere, very proficiently. He's even starting to pull himself up onto things. We allow him to explore while we watch him. It has been though, that he'll crawl around, and then start grunting and making a foul face and starting to get very upset. This goes on off and on throughout the day.
Could it be boredom? Or just frustration with his in between stage of not being able to do everything his body wants to do and is trying to do? Like reaching objects, climbing, etc?
He's eating, sleeping, and napping well. So I've ruled out hunger and tiredness.
Thanks for any insights.
