Second kid

Looking back I did SO much with my first when he was 2. We did letters, numbers, themed units over summer with arts and crafts. He was SO smart. (Granted this was 2020 when Covid hit and we were stuck home) Now I have a second and he’s 2. I haven’t had a chance to do any of that with him. He’s smart in his own way but definitely does not know as much as my first did when he was 2-3. I feel so bad my second is not getting the same experiences as my first at this age. It’s just so hard to get up and get things done nowadays. I keep beating myself up over this and looking back at all the stuff I did with my first. Is this just life with more than one??
