You are the only one with a young child.
Husband, is busy hanging out.
This is an adult, trip.
Not a 4 year old trip.
So there is a conflict.
Then, this is the 1st time for Alyssa to see these "strangers." Even if it is her cousins. She doesn't know who they are and at this age a "cousin" is still a very abstract idea for them etc.
And she is out of her routine.
And she is guaranteed... VERY overtired.
Overtired kids, are fussy and have NO tolerance for things.
And this is basically a pool/beach trip.
Some people even adults, get tired of that. Being out all day at a pool or beach... is... tiring. Even for me and I am an adult and live where there are MANY beaches and pools. Being out all day at one, is tiring.
AND the sun... and heat.... can EASILY EASILY make a person, tired and overtired and hungry. HUNGRY.
The heat itself, is very draining.
I live in Hawaii. I know.
Even if you are just hanging out.
Even if raining, it can be hot here.
You have a young child. She is having to, be like an adult. She is not. She is only 4.
You.... then need to, do what is needed, to help her.
Craft projects are not doing it.
She needs, rest. And not bustling around. Even if on a trip.
When she is tired, excuse yourself. You don't have to be apologetic. She is only 4. At 4 years old, both my kids were still, very regular nappers. AND needed it. Daily. If not they turned into Jekyl and Hyde.
It is not her fault.
And, her meal times are going to adult, timing.
Not child timing.
This is an adult trip per everything that is going on.
And, playing all day for a young child, is very tiring. They cannot possibly go on and on with no break or nap.
When people are guests at our home, they also have their own, needs/routines. And that is expected. They do what they need to, per their own child.
And, when we have guests here... I don't make my own kids, go according to them or their schedules or activities. I go according to MY own child. And I tell them that THIS is our routine/plans/needs per what I need to do and when.
Kids, do not have to be entertained all the time constantly every minute.
That is very exhausting especially when on a trip.
They NEED... DOWNtime too.
Even more so, than an adult.
Sleep deprivation.... causes a ton of problems.
Especially for a young child.
It lessens... their tolerance for everything. And they get fussy.
Can you just do something else with her?
Even just go in some shade and rest or hang out with her?
Or go for a walk etc.
All I know is, being out in the sun, all day everyday at a pool or beach... I would get tired of it too.
