‘When ours (also with asd) was 7 we first did a trial-run with him staying with GP and us in a hotel 5 minutes away in case anything went wrong. It all went well and now spending 3-4 nights with GP a couple of times a year is perfectly normal and fun for everyone.’
This is a sound gentle approach for developing a child’s sense of independence. By 8yo, staying away for a night is an adventure.
A nearby hotel, with a family room, is the right level of distance for an emergency quick dash to or from home. Not too far, not too ££.
A scoff-up breakfast buffet is a kid’s exotic banquet - endless sausages & pancakes, toast hot off a conveyer belt, little pots of jam & ketchup etc. Wanton plate piling with no exhortations to hold back or finish up, what’s not to like for a hungry kid?
Obviously 4yo is young, especially if the child needs support through the night.
As your DC settles more, Would you consider a brief weekend city break away with your In laws? Have your iLs babysit the kids in situ while you & DC have a date night? Build up the connection & camaraderie between all of you, it’ll bring joy, ease & future dividends.
Your iLs love your children, more than anyone other than you & their father.
It is an unconditional love for the children particularly when they are young, it’s all the ‘just’ adult stuff of life that gets in the way: time, distance, money & family dynamics etc.
They are squaring up to the challenges of early retirement in a lovely place but possibly that bit too far away from family, friends & community, maybe even missing work. Possibly they are having some buyer’s remorse - that’s their deal - & their grandchildren represent a loving closer connection, a future contentment they are yearning for? Bet they’d love to park the dog so they can get about a bit now they have all this time on their hands - city break maybe?
So, although MiL is not yet up to speed, loving energetic grandparents are a blessing. Nurture the connection, be direct & informative with kindness.
Do not look a ‘gift’ grandparent in the mouth.
