@Kittycaz, my son (Bastian) was the same with only sleeping if my husband or I were holding him. He'd scream bloody murder if put down, even for minute. We took shifts so the other could get some sleep. My husband took nights, meaning he did all the holding/cuddling, nappy changes, burping, settling, etc. And just brought him to me when he needed to feed, I'd half wake up, feed, go back to sleep. Then in the morning I'd take over and to 100% while hubs slept for about 6 hours, then he'd get up and we'd share the evening hours until I went to sleep. etc. It was exhausting!
As I knew his paternity leave time would be coming to an end, we had to figure out how to get Bastian into the Moses basket or bedside cot. At about 12 days old, I started putting him in the basket after he'd fallen fully asleep on my chest and let him lay there until he woke up, often with my hand resting on his tummy. Part of his issue appeared to be that he is not naturally a back sleeper, so his startle reflex was in full force as he'd sort of lean from side to side while laying down. I tried swaddling with a light blanket, but the kicked those off in minutes. I tried with the Velcro swaddles and he wouldn't settle with arms in. I eventually tried the Velcro swaddles but with his arms out, so basically just a wearable blanket. This combo gave him enough stability and security to stay on his back but still have his arms free. It also gave me some peace of mind that he wasn't going to kick a blanket over his face. It still only worked for short stretches, but we kept trying and after three days, he was ok being put in by he basket after being fed and burped when he was still milk drunk. He's still not pleased about being put down when not in his milk sleeps, but at least it's allowed us to stop the 24-hour holding. Now hubs is back to work, i have Bastian pretty much all day (hubs works from home so helps me with looking after him when I need the loo or something), then hubs takes over as soon as he's finished with work so I can have a couple hours, then we split time while doing dinner etc, and I take back over at bedtime. I've just been trying to very gradually increase the time sleeping in the basket and that seems to be working. He's in there all night except feedings now.
Right now hubs is sleeping in the other room and I have Bastian in the basket next to me in bed (we're sideways across the bed with the basket between me and the headboard so I'm sure the basket can't tip off the side). I hope to start transitioning to the bedside cot soon. Fingers crossed.
Anyway, tiny incremental changes is all that's working for us. I'm not sure if that helps at all, but I hope so.
Someone told me that with babies, the minutes are long but the weeks are short, and I'm finding that to be true. I can't believe that Bash is 2 weeks and 2 days old already! But those minutes sure are long! 🌻
