I think you probably need to speak to the manager, is it a big nursery sounds like it if they’re handing over the wrong baby. My son started 6 weeks ago before he was one and he actually puts his hands out to go to the staff now, he cried for the first few weeks but only when I said bye. He does drink less milk when he’s there than at home but will have a full bottle. It sounds like it’s not a very pleasant setting I would be certainly looking into another provider and I’d maybe be letting ofsted know about your concerns! Really sorry your going through this xxx
Tbh I definitely don't think you're overreacting. I would ask to have a meeting with the nursery manager. Calmly explain all the issues above and see what their response / solution is. Maybe depending on their response you might want to keep going to see if care improves such as not sending photos with snot around his nose etc then but if you're still not satisfied or if another thing like any of the above happens I would definitely pull him out of the nursery.
I had a really similar experience with my little boy’s first nursery. It’s hard enough handing our babies over in the first place but when there’s that niggling feeling that something isn’t right, then go with your gut. I sent a polite email outlining the concerns I had and just explained the nursery wasn’t the right fit for us as a family. He’s now in a different nursery and it is just a completely different experience. He seems to love it, the staff are so professional and great at communicating with us. Pulling him out of the first place and finding somewhere new was the best thing we could have done. I felt worried about him all day when he was at the other one (I knew no one was intentionally not looking after him properly but things just didn’t sit right with me.) Hope you sort things and that you and your little one are happier. Xx
