As much as I ADORE my little girl, there are times when it feels like it all sucks. Periodic twinges of pain when I feel sad about the things that she is not doing yet, and may never do. Days when all the appointments and worries and stresses feel overwhelming. Days when I just want to talk about it all without feeling like it means that I don't love her through and through.
These moments don't make me a bad parent, and don't diminish my love for Cora. They just make me human.
Don't underestimate your child's intelligence. A cognitive disability or limited verbal communication does not mean that your child is not smart.
Assume that your child can understand you. Especially when it comes to ice cream. Assume that your child understands everything about ice cream, including signs, finger spelling, and all of the code you will come up with. Children seem to come equipped with a radar for these things. At least mine does.
