Hi OP, yup I hear you. Have 2 DC with similar age gap and some days are wonderful and some are just overwhelming / exhausting mad chaos 🫠 the bickering, the whining, the mummeeeee (insert gripe here), the meltdowns, the trying to get everyone ready and out the door like herding cats... 🤯
For me a few things helped, the first and biggest was caring less about the mess, Like A LOT less. I want to say this was an easy process, but the truth is the clean freak in me was not easy to ditch. She was one stubborn, determined B. It was an ugly fight that raged on and on but in the end I crane kicked her ass out the 2nd storey window and she gone 💀. No regrets! I am typing this now from the nuclear crater that used to be my lounge BUT my brain is happy! 🤩 Is it perfect? Nah. Would it be better if we lived in a sane tidy house? Yup. Am I going to care that it isn’t? NOPE! 😁 Honestly it has been the biggest game changer and finding I can enjoy time with the kids much more without that annoying bossy moo in my head pointing out all the mess, scudge and clutter (mother, is that you?? 🤔) It’s hard to let go, but embrace the mess! (For now at least)
Secondly, getting a buggy my LO liked, it was a freebie and had a different kind of bar across the front that made it a racing car apparently. Made it a different happier experience to go in it. In your case if buggy is unlikely to ever be a happy place how about a push along trike?
Someone said upthread about having somewhere to go which is contained and will cater for both levels of play which is a sanity saver like enclosed play parks or soft play. Also you might find toddler groups in the summer open out to outside play areas too, which could be more appealing for your nearly 5 yr old? Where I am there are a couple like this that open up back doors for outside play.
Do you have a garden or somewhere you could pop a water table? Little sand pit? Anything that could keep their hands busy so you can be off duty for a wee bit. Even an old washing up tub full of water on the patio and couple of brushes for water painting is a good one, or ‘painting’ a fence or wall in the same way.
A friend had the ingenious idea of a fixing those big bubble wand tubes to the garden wall or fence (upright), then little ones can dip the sticks and blow bubbles themselves freely without you having to hold the tubes and follow them round/ help dip etc (they can hold it themselves in theory but usually just ends up with it getting tipped out, especially with younger DC)
So a couple of ideas there and sorry if it’s duplicated, I haven’t read the whole thread.
Hope you’re having a good day today OP and Hang. In. There! x
