My 2.5yo was sick yesterday (about 2pm) and hasn’t been able to keep anything down since, even sips of water are coming back up within minutes. I’m wondering when/if we should call 111 or if it’ll pass on its own? She slept through the night after being sick early on and she has slept a lot today (very unlike her) but I guess she has no energy and it’s good to try sleep it off. But I’m worried she’s not eaten anything today. To make it worse, we have a 3 week old baby at home too, we are washing and sanitising our hands all the time but realistically is there anything else we can do to try ensure we don’t all come down with it?
