Has he laid down yet? I haven't seen him. Yrs ago I had a foal not lay down for two days, then he was so tired that he just fell down and the look on his face was relief. I didn't know then that you can teach them to lay down, once in a while I get a foal that doesn't lay down for a long time, I gently lay them down and rub on them and make them stay down and relax. I'm just mentioning this in case he's one like this.
I hope you put pictures on without the blanket, I'd love to see him close up, I missed the birth too, woke up at 1:15 our time. Congratulations, he looks so straight and healthy.
