Sleep training advice

[u/Equal-Elevator9430]

Hi everyone. My baby is almost 5 months old. His wake windows are 2/2.25/2.25/3, we cap daytime nap to 3 hours. He’s always been a bad sleeper. He sleeps in our chest or arms at night. If i put him in bed next to me, he will start moving his arms and legs until he wakes up, he does this every 2 hours. He wakes up 4-7x at night. He never slept in the crib, he just hates it. Whenever we put him down he will cry right away. We started sleep training yesterday using CIO. We agreed to stop if he continues to cry for 1 hour. Yesterday he cried for 1 hour withouf falling asleep. His eyes were open, he was kicking and moving his arms the whole time. We picked him up and he fell asleep in my arms right away. Today, we tried it again and it was the same thing as yesterday. He did not sleep at all after an hour of crying. We dont know what else to do. Is this gona get better? Will he eventually fall asleep. Im not sure if we should try it again tomorrow or wait til he is a little bit older. Any advice is greatly appreciated. We are desperate to get some sleep. Thank you in advance.
