It must be distressing for you. I know very little about this, but I think he is at an age where he may find it hard to adjust to being away from you regardless of what nursery are doing. I understand as a general rule the younger babies are when they start nursery the quicker they adjust. Also there are five days a week in a row he's not in and able to forget about it, so that will be a factor. Hard as it is, I would give it more time. Are the nursery worried? Also, the not sleeping thing probably normal while he adjusts to a new environment. Ditto adjusting to new food. Good luck!
I would be worried, who wouldn't. If the nursery is a good nursery (and you say it is rated outstanding) then i think you should have a chat with the manager and explain your worries and let her come up with a plan of action.
My 14 month old has started nursery 2 months back, 2 consecutive days a week. And he's not settling in! He is tearful most of the days and doesnt eat and sleep as much as he would when he's home. The key worker that nursery assigned to him was off most of the days when he started and now again due to health reasons she's away for 1-2 months. So throught this time my baby has not had the opportunity to bond with one person. Each day there is a different girl assigned to him and this system is not helping him at all! It is an ofsted rated 'Outstanding' nursery and is indeed a good nursery and other than this one issue I have no complaints at all. I mean even when he is tearful he is given lots of cuddles, though with a different worker each time!
I am feeling disappointed and anxious. Each day he is nursery I am not able to concentrate on my work and keep ringing nursery, only to be told he's tearful today! Should I consider changing the nursery.
