Terrible toddler!

Stephanie

So my son will be three in August and lately he has been so terrible!! Tantrums galore, throwing and hitting when he’s mad, and just not listening! We had a baby in April not sure if it’s jealousy or just toddlerhood. He is language delayed so it’s hard to talk to him. He understands us but I feel like the second I tell him no he has to do it

Anyone else go through this at this age? I’m sure quarantine isn’t helping
