Hard to Digest

No matter how much I know Brandt is delayed, no matter how aware I am of the situation, no matter how much I see coming--nothing can prepare me for having to face the harsh realities of the situation--big or small.
With Brandt's 1st birthday just a few weeks away, I have been getting very nervous/ anxious with his school situation. Turning 1yo means transitioning into the toddler classroom. However, I have had a pre-conceived notion that he might not be able to enter the toddler room because he wasn't walking yet. Luckily this is not the case, though the true reality isn't much more hopeful.
I sat down with the director of his school today to find out how and when the transition would take place. Come to find out, she actually wanted to talk to me about the same thing. She reassured me that there are plenty of children that go into the toddler room before they can walk. However, there are some things that they do expect the toddlers to be able to do that he cannot. They expect the toddlers to be able to pull up, transition to a sitting position, and sit in a chair (rather than a highchair). Because he cannot do any of these things, he is not able to transition. Particularly with him not being able to sit in a chair, there are certain concerns for his safety.
While I completely understand where they are coming from and sort of saw it coming, it still wasn't easy to hear. No one wants to hear that their child is not progressing. No one wants their child left behind. It sucks because, truly, his school doesn't even have a high bar to meet--asking him to do those few things doesn't seem like they are expecting too much. It just sucks. This whole situations sucks.
How many more pieces of reality am I going to have to face? How many more things am I going to have to come to grips with? Is this just the beginning of my son being left behind and me being let down? How many more hard truths of reality will I have to digest? When will this end.... when will this end.....
