My son turned 2 in October, around 12am (Monday night/Tuesday morning) I heard him cry in bed and be sick so I ran to him and sorted him out and cleaned it up etc. He was sick a couple more times while I was doing this. Took him downstairs so I could keep an eye on him so my partner could sleep and was sick again. Put him in our bed as he was tired and wanted to sleep (I hardly slept), he woke about 2am and was sick again but was more watery as he didn't have anything else to bring up. That was when he was last sick. This morning he's had a few plain crisps and some water but doesn't want any food that I offer him and is very lethargic, drifting in and out of sleep and definitely not his usual whirlwind self. I'm a first time parent and have no idea what to look out for if he gets sick. He's currently asleep again now and has a slight temperature from what I can feel (our thermometer is broken). What is best for him? Do I just let him sleep and keep offering him food when he wakes up? I feel so helpless
