I remember when the "over it" bit happened to me - just after a year here too.
DS fell over and I just looked at him and said "your own daft fault, you can walk well now and you're just tired; you should sleep at night." (He didn't nap in a half-hour walk either.) He was wailing at me! A friend looked at me, and told me she was taking
DS for a half hour so I could sit down with a drink.
So I had a drink and a chat to friends and was refreshed enough to cope with
DS.
Could you do that? Even just a half-hour of no children can make such a difference.
