LO had two epic tantrums today. One when I was trying to put him down for his nap thisafternoon and one just moments ago when DH took him up for a bath. DH was away last week and came back with his parents. While he was away, our baby sitter helped out with bath time. She did his nighttime routine for the 4 nights DH was away. LO was wasn't happy about it but never got into full tantrum. When DH got back, things went back to normal. DH is usually the one who puts him down for naps and bedtime on the weekends. Today was the first day I was the one who put him to his nap since DH returned. He threw an epic tantrum as I tried to bring him upstairs. He always stalled when we read him stories but he was always willing to go upstairs on his own. I finally got him into bed and he babbled the entire time and then started crying. He never did end up taking that nap. So I though that maybe tonight, he'd be okay since DH will be putting him to bed. But he threw another epic tantrum once again trying to get him to go upstairs.
These tantrums were so intense that I wonder he he has some sort of neurological problem.

Could DH being away have caused this? Or is it because we have visitors? Perhaps it's because this is leftover frustration from our babysitter putting him to bed last week?
