Niall woke up still wrapped in his car print blanket with his matching nightlight still on in the corner. He sighed sitting up. He loved being the 'baby' , but in the headspace of a six year old he really wasn't dependent on the boys like he wanted to be, but asking them to do more was selfish of him. He dragged himself out of bed, deciding to carry his stuffed monkey with him, not a big difference but it was something unusual. He went to the bathroom and then pulled up his pajama pants. He left his monkey on the counter and washed his hands, purposely not flushing and getting his sleeves a bit wet. He smiled to himself and dragged his monkey down the steps with him to the kitchen.

Liam had woken up when he heard Niall getting up and was downstairs making some breakfast, knowing the others would not be up for awhile after being out so late. He smiled as Niall came in with a stuffed animal still in his hands. "Morning Nialler, sleep well?" He asked, ruffling his hair as he passed
Niall sat down and shrugged, holding the monkey to his chest now. With the want to be in a smaller headspace, Niall didnt feel like talking much at all.
Liam didnt make a big deal out of it, thinking the boy was just still waking up. He put a bagel toasted with butter cut in half in front of Niall and got him a glass with mickey mouse on it full of milk. Niall stared at it with a frown. He picked at the bagel for a minute, getting butter all over his mouth and then reached for the glass, but it spilled over from his slippery fingers. "Daddyyy" he whined standing up
Liam raised an eyebrow at the change in Niall's voice but quickly cleaned up the spill "there we go, now finish your breakfast buddy" he said smiling.
Niall didnt even look up, just huffed and took a few more bites before running off.
When all the boys were awake, Niall still wasnt downstairs. This was unusual since Niall was always one to watch cartoons in the morning or lay on the couch. Liam told them about Niall's changes just at breakfast and Harry decided to go find him.

Niall was in his room playing with the few toys he had gotten, a set of legos all over the floor and he was sucking on one as he rolled his cars around.
Harry gasped "NIALL NO!" He said sternly and pulled it from his mouth "you are gonna get hurt!" He scolded
Niall's bottom lip trembled "sowwy" he mumbled
Harry grabbed his hand and pulled him downstairs, not having heard his voice.
The boys were all sitting down watching a movie. Harry sat Niall down with a blanket and then went to make popcorn. Niall just wanted to cry, he didnt get the response he wanted yet and the didnt know how much farther to take it.
When the popcorn came out, Niall was handed a kiddy bowl and the others each had a bowl. If he was a baby, Niall wouldn't be allowed to have popcorn...
He started obnoxiously shoving it in his mouth, some pieces falling on the ground.
"What has gotten into him?" Liam sighed
