Covid-19 lockdown kids activities
You specify "little ones" but prettens and midteen kids also need to keep active.
I imagine 'little ones' means early elementary k-3rd grade?
Most of the time if you give them something it will keep them occupied till something else distracts them.
When the child starts to ask 'why' about everything and their imagination awakes, things to keep them occupied gets a bit more difficult.
Give them something which enlightens them about the world around them.
Give them something that inspires imagination.
Puberty changes their focus.
Give them something to teach them about how their body changes.
Give them things which inspire their self-confidence and empathy for others.
If you are dealing with the "insanity in a box" from your mid-teens,
They need alone time to reflect on their changing emotions and feelings.
They need wisdom from you on how to deal with stress and the relationships with their friends which may be waning because of sheltering restrictions.
Believe it or not, they had a life outside your home and it has changed.
They need their phone and their facetime with their friends.
Give them guidance and allow them to socialize naturally as possible.
Help them thru difficulties with love and wisdom but allow them to experience their own mistakes. Teach them how to not repeat their mistakes.
Listen to them. You have two ears and one mouth, listen twice as much as you talk.
