Hey all. I'm not to sure what to do about this situation. I'm not sure how to terminate........How does it work when u term one sibling but not the other??

I have a 1 yr old bother and his sister whose 3 yrs old. The 3 yr old has been here since she was one and her bother started last November so has been here for three mths. No problems with the sister she's great. But problems with the bother. Constantly cries. After three mths he is STILL not adjusted into daycare. It's had to bond with him because he always always cries. Finally he can play all morning just fine and smile and laugh and be happy that's a big improvement as before he cried all day expect for nap. But even though he can play fine he'll cry through EVERY transition. Cries through diaper changing. Cries when I pick him up to put him at the table to eat. Cries when I get him dressed to go outside or undressed to come in. I've written a post on him before and his crying and it is totally behavioural. It's stresses me out big time!! I know he can play fine but I just want to change his dam diaper without him screaming in my face. And the poor kids that have to hear that as well all day. I just don't get it. At playgroup he'll cry because he can't see me then crawl over to me to be picked up??? But yet he cries when I have to pick him up to change him....ugh!!!

After three mths and me in tears today I have decided to terminate. I truely believe he will thrive in a day home with less children and a provider that can spoil him all day like his parents do. I just can't do it anymore. The crying is to much. I've tried anything for three mths. Three mths!!! Sigh. I'm in tears because my heart goes out to his sister. She loves it here. Has best friends here. Says I love you XXX to me all day long. But if I kick brother out mom won't want to do two daycare drop offs so obviously she will pull both of them out. It's just sooooo unfair for the sister to go because of her brother . But it's what has to be done so I can enjoy my work again.

So my question is...... In my contract it says I must give three wks notice to terminate or I can terminate on the spot if a child fails to adjust in a normal,amount of time. So with the bother I can term right away but what about the sister? Im going to say I can keep her but I'm sure mom will find other care for both of them. So do I just term and let her pull sister out when other care is found but brother can't come?
And she'll have to give three wks?? How does it work when u term one sibling but not the other??

Another question is.....although I am allowed to term on the spot for bother not adjusting I do want to give a wks notice. I can handle a wk more and just to give mom time. But can I do that?? It says three wks notice or on the spot for a variety of reasons nothing about a wk?

Thank you for your insight. Feeling so drained and stressed from all of this
