Emzy,
Sweetheart don't beat yourself up over how your little munchkin is with you, she loves you to bits and knows what a fab Mummy she has.
They do get grumpy, it can be from teething, change in needs like getting hungry, tummy ache, too tired, anything really!
She prob just settled to dh as he was a change of face and she knows he couldn't do whatever she wanted because she knows even at her age that everything comes from the Mummy person!
Teeth are usually the problem, they can sit under the gums for ages before they show!
Sophie used to scratch out at me, and never settled with me, she just seemed to do nothing but cry for me, I used to make her comfy under her mat or something and leave her while i went off and did something else, she had her moments of being totally lovely, and i am sure Holly is just feeling grumpy for something and taking it out on you, as we all do take it out on who we love because we know we can get away with it, so does she!
Don't take her behaviour to heart, i expect she was just over tired, and disturbed by sore gums or something, and she wants sleep as much as you so will just get grumpier with little sleep, it is a bit of a never ending spiral, perhaps try and sleep with her during a nap or 2 if she will settle today
Louise, as long as she is not crying out, or looking like she in in discomfort above normal rumbly tummy, and the poo is not like constantly flowing, and she is having plenty of fluid either her usual milk or cooled boiled water, or some baby juice, that is all you can do.
If she is upset with it, in pain, and not taking fluids then call for advice, but if none of those things apply, and you are ok with it then just see how long it carry's on for, anything over a few days the doctor or hv should be told, they may suggest something.
Although the colour represents something it is more how she is in herself
Lbb hi, hope lo feels better soon, these bugs seem to be really hanging about
