My little one has been a nightmare since he got over his cold that he had Monday-Friday. We went out of town Friday night and left him with his grandparents. He was great for them but as soon as we picked him up Monday morning all heck broke loose. I figured maybe he was mad at me for leaving him for a parents weekend away (first one since last summer) and missed us but he hasn’t let me sit him down since yesterday, won’t lay down for naps with out throwing a screaming tantrum, wants to throw things and is just overall being a toot. Is this because we left or does this sound like a regression.
