Hyper active toddler

I love our second child (20 months) to bits but gosh he has energy for ten. From the moment he wakes up, till the second he goes to bed he can’t stop moving. Has to climb every chair, table or whatever is high in the house. Can’t be left alone for a second and we had to baby proof our house to the maximum but it still doesn’t feel safe enough regardless. I go to the park, playground or any place he can safely climb/walk/run around in almost every morning for a few hours but that still doesn’t seem enough because once we are home, he can’t stay still. I can’t read him a story or even chill for a second with him.. ifs constantly. He was a very different child a year ago, the calmest baby I ever had… little did I know how that would change.

Our first one wasn’t an easy baby, but she’s a dream toddler compared to him (didn’t care to climb, run away from me or investigated the house etc). When will this mellow out 🙃?

He naps for an hour and a half during the day and sleeps through the night for 12 hours so he isn’t over tired btw.
