Need some help

[2beautifulbabs]

I'm posting on here for some advice and some help basically my 2.2 year old DS has recently been throwing up when he's getting worked up

The first time he done it was a shock and at first I thought he may have a bug I was busy changing my DD and he was by my side whinging I thought nothing of it until he threw up projectile vomited over himself the dinning table and floor he was fine after he calmed down and wasn't sick again for ages
Then a few weeks later same thing happens can hear him coughing/crying in his own bed so go to him thinking he's woken up upset and he's thrown up all over the bed and himself he's gotten so worked up he's trembling and really hard to console so after that we put him in with me and DH goes to sleep in back room
DS starts retching again and throws up but once cleaned up he finally settles and goes to sleep
So since then we have had him in with me we decided to try him again in his own bed when we felt he was back to himself again the same thing happens last Friday he's woken up coughing and I know he's thrown up again and he has again in such a state he's screaming and trembling as I'm trying to get him undressed and clean the sick off him in the end I had to wrap towel round him and sit on the floor comforting him until he calmed down
We've been having difficulty with him sleeping and last night after him waking and crying and then setting his little sister off I had to ask my DH to have him as he was setting his little sister off and disturbing her sleep
It was an awful night he kept waking sitting up bolt right then fidgeting just not settling
We come down stairs about 6am he's given juice as he was whinging for some next thing he's sat next to me on sofa and he starts retching and projectile vomits on me and himself covering us both and understandably starts crying again manage to calm him down and get myself and him re dressed etc

I don't know if this is part of an underlying issue his speech isn't very good he's gone from saying Hello, Hiya, mummy, Daddy,Cat,Car,Dog and a few numbers to hardly saying anything now
I'm really worried I've already raised my concerns with his speech to Health visitor and I've just rang them again about the throwing up so I'm hoping they will look to assess him soon or give some advice as I'm lost I really am I don't know whether to call the doctors and see what they say or will I just be told it's toddler tantrums 😞

I'm also unsure if it's because of his little sisters recent arrival that it's thrown him out she's currently now 13 weeks old he's always been nice to her never shown any signs of wanting to hurt her but also at times he doesn't seem interested in her apart from her toys or dummy

He recently started a pre school group as we wondered if he were to start socialising more with children his own age it may help with his speech it's still early days and again I'll be chatting to the nursery staff to see if they've picked up on anything
I'm sorry for the long winded essay I guess I'm just after advice from other parents if they've been in similar situation and if it's later come about to be something like autism or something else

Is he being left at the preschool group? If so, I'd take him out of it. He's clearly unsettled--hopefully it's just the arrival of his sister but if he's been (to his mind) pushed away as the new baby is here and now you're sending him away for parts of the day, that will probably have made it worse. Starting childcare can be a stressful time for any child and result in disturbed sleep, even without a new sibling. However, given the strength of his reaction, I'd be concerned that something very untoward was happening to your DS, possibly at playgroup, possibly elsewhere. Massive changes like that don't just happen and people who work with children are trained to view them as a sign of potential abuse.

Thank you for your reply I was going to have a word with the nursery as it's only 2.5 hours in the morning he goes but I wanted to see if they had picked up anything.
It's only me and my DH that care for our son and daughter as our families live a good two hours away from us and I fully trust my parents and my husbands so know it's not abuse of any kind.
Only thing I can think is it is the arrival of his little sister.

If his sister has arrived and then you've put him in childcare for the first time he is likely to feel that the two are connected and may be feeling insecure in his position in the family.

Abuse can happen at playgroups too. I'm not saying that's the case, but it can. If he's being shouted at and having a rotten time that'll cause issues. It may well be nursery + sibling though.
