Anyone dealing with a huge spike in tantrums and meltdowns?

My son turned two on the 18th of August and I swear since about the first or second week of August he has at least 1-2 tantrums every hour during the day. I have a 2 month old too and I’m struggling with feeling burnt out all the time and I know I’m not doing an amazing job addressing all of his tantrums. Any tips on how to handle tantrums with a two year old? He sometimes hits out of frustration, he screams as loud as he can to try to get his way and when we don’t give in he melts, yells and cries. I know it’s pretty typical for a two year old, but the frequency of them has been very hard lately.
