I just wanted to tell you that my son did the exact same thing, like I could have written that exact post a month ago!! my son is 16 weeks today, and well, from like 10ish weeks to about 13ish weeks he did that exact thing. He would sleep all night, wake up in the morning around 6, eat, and go back to sleep till like 9 or 10, which is lucky for me since I am NOT a morning person. Then throughout the day he would take 2 good size naps, maybe a smaller one, and then come the time Daddy gets home (between 5 and 6) he would cry the rest of the night. I called him my champion fighter because he fought sleep like nothing I had ever seen!! It just seemed to pass. The crying in the evening got less and less, and he napped a little less during the day (probably because he is getting older) and now he still has the same night and morning schedule, and sometimes he naps during the day and some times not (the days he doesnt are a struggle by the end of the day, as he is crying because he is so tired) but needless to say, the incessant crying in the evening until bedtime has pretty much stopped. The only time now that he cries in the evening is right before bed, at about 9 and that is because he hasnt napped properly and is way too tired. I guess what I am trying to say, is I went through the same thing just a month ago, and he out grew it. He got better and now we have very enjoyable evenings together. I would just suggest to give it time. Good luck! I hope he settles down!
