I know IABU.
My second and youngest child is starting school this September and I'm struggling to manage my feelings about it. He's ready for it and I'm excited for him, but the thought of him not being with me on my day off is making me feel so upset at the minute. I didn't feel so bad about my eldest starting school but I think it's due to a number of reasons - he's my last child, this phase of my life is now over, and I genuinely will miss him.
Please talk me round and tell me about all the reasons I will appreciate having that day to myself! I feel like I've lost my identity.
