My 6 week old sleeps well of an evening but not very well for naps. When trying to get him to sleep he gets angry, cry’s and throws his arms and legs about. I have tried various other ways to get him to sleep. I’m worried that this is going to get worse as he gets older and it really looks like he’s throwing a tantrum. I don’t believe it’s pain because as soon as I put him down he stops. Any advice welcome. Thanks
