We just had the same with a day of a sickness bug. My boy was sick quite bad 4 times in the evening so I just gave him water and slept with him to keep an eye on him. As above…. I’d try the milk but maybe give it him an hour before bed so if he were to get ill from it he’s still up with you. Depending on how you think he is just keep a close eye on him. The last thing I wanted was my boy throwing up while asleep in his cot Hope he feels better tomorrow xxxx
We had to skip milk for a few days when my daughter had a sickness bug as guzzling it down made her throw up after a little while. After a few days, just introduced it but had to keep taking the bottle away so she didn’t down it all in one go haha
How long since he was sick? If it were me I would offer him milk at bed time and just keep him sitting up after for a bit to make sure it goes down x
