Is he eating or sleeping in your care? If yes, I would consider that a sign that things may get better fairly soon. Does the child sleep in the hammock thing with you? I personally wouldn't use a weird contraption in my daycare. I have many attachment parenting children in my care, some had never slept in a crib before and they sleep perfectly fine in a crib in my daycare. Kids are adaptable and will quickly learn new ways in new places so I would start a new child off in the manner I want them to be sleeping in long term.

Anyways...it can take a good 1-2weeks before the crying subsides, sometimes longer. Different children cope in different ways. It sucks, it is brutal on us, hard on the other children but it CAN be perfectly normal. That said...some children just can't cope and adapt and it is on you to figure out if you think this child will or not. Pull the plug when you see fit. There is nothing wrong with telling a family this just isn't going to work.

Hopefully the child eases into care in the next few days and it gets easier for you all. Just find ways to cope. I had a child start and he did best if I completely ignored him when he was completely melting down at the gate. If I even looked that way or spoke to the child he would get worse and go longer. If I sat nearby playing with other children with my back to him, he'd stop and come over to join us for a bit (tear free). It sounds mean, goes against what we as caregivers want to do but for some children it is the best thing to do. I also found that sometimes a firm "stop" would break the crying cycle and reset their mood for a bit.

I also keep the first few weeks as transition free as possible to help the child. We don't go outside as that is just another set of transitions and a new place to adapt to when already overwhelmed. I do extra snacks as they often don't eat a full amount in one sitting and they are just much calmer with some food in their bellies.

I did luck out that I never had a child cry/scream all day. They all ate and slept (though short naps) from the start which helps wonders. It is utterly exhausting to listen to crying/screaming. BUT...my child that took the longest and was the hardest to adapt is an amazing child that knows all routines and is thriving now. It is amazing how well the child has adapted in just 3 months with us.

Hang in there.
