Not sure what to think of this. We went out for lunch on Wednesday to the pub, all ate different meals. DS (6) had fish and chips. 6 hours later he had a bowl of pasta, most of a kiwi which he normally loves, but said that it was too ripe and left a quarter of, and then refused Yule log. Said 10 minutes later he felt poorly when watching TV. Tried for a poo but nothing. Went to sleep and half an hour later was sick in his bed, then much more in the toilet. Went back to bed very happily, slept soundly all night and was as right as rain the next day. Put it down to something he ate, query kiwi allergy. Played in close proximity to his brother, building Lego with heads together all day. At 5pm said he was starving, but we didn't manage to get dinner on the table until 5.45pm by which time he was a bit nauseous so didn't eat the chicken, but did eat a bowl of rice and a banana. Put nausea down to hunger, felt better after dinner. Slept well.
Friday he had a slightly reduced appetite but generally normally playing, kicking balls in the garden etc. Was more sleepy than usual in the afternoon. Pizza for tea with veg including a Brussels sprout (cooked fresh, not leftovers). Went to bed happily and slept all night.
Saturday morning he was really bloated with a rock hard stomach and had a loose poo before we went out to parkrun where he ran 5k. Really eggy farts all morning. Few loose poos during the day, 2 mini accidents in pants. Generally more quiet and withdrawn than usual, but still playing with his brother. Rock hard stomach all day, very unusual for him. Pain just below ribcage at about 4pm, just after eating a Malteaser. Wasn't particularly interested in food but did have a wrap with a few crisps and grapes for lunch. Couldn't manage his Chomp bar from selection box. Watched the Cebeebies panto before tea and was giggling away to it. Said he felt really really tired, usual for him at that time. Sat down for tea at 5.45pm, took one mouthful of breaded chicken and dashed to the toilet, lots of water came up (his 3pm cup of water I presume). Wanted to go back to the dinner table and finish his tea but I said it probably wasn't a good idea. Now sitting on the sofa feeling much much better, still not quite normal though. Stomach feels much softer and apparently doesn't hurt any more.
Noone else in the house is ill. Everyone feels normal despite being in close proximity to him all week (off school and work).
I just don't know what to think, was it food poisoning from the pub? Kiwi allergy? He hadn't had a poo since Tuesday until this morning when it was diarrhoea, perhaps he's constipated? Would that cause vomiting 72 hours after the last bout of sickness? He's normally a regular once a day kind of guy.
Any thoughts? Grateful for your help, am concerned about him.
