1. It will never come back.
It's a non-renewable resource and you must use it wisely. It's a great thing to spend time with kids because the beautiful memories created with them playing outdoors, sharing stories, teaching them some skill will all be remembered by them throughout their life. We don't always remember the toys that were gifted to us, but we remember the memories we had with parents. Thus, it is important to realise that materialistic gifts can wait; time cannot.
2. You cannot buy the time
The phrase 'time is money' is indeed true, yet; not everybody realises the value of time unless it is lost. So when you compare spending quality time with kids against the fancy remote-controlled toys, you'll realise that time really cannot be brought back.
3. It increases the bonding
This is one of the major perks of spending time with the kids. We must have seen many a time that nowadays kids spend a lot of time with their gadgets and toys because the parents are working. As they grow up, they continue the same habit and eventually there's no dialogue between parents and kids. So if they have any problem, they have a hard time sharing things with parents because they're never used to do so. Spending time thus help kids become more sharing and expressive.
4. It highlights the priorities
When parents spend a lot of time with their kids, they understand their priorities and also make kids feel special. The quality time also helps parents chalking out their priorities and planning the day accordingly. It's a give & take - parents value their kids and vice versa.
There are a lot of ways in which parents can spend time with kids - travelling, sharing their day to day experiences, going out to eat, watching the old pictures and telling them the family stories, or playing indoor games that will also develop their skills.
In this remote-controlled age, some things still have their value and cannot be replaced. You quality time is one of those, make sure you spend a nice time with the kids for their overall well-being.
