1 year old..... tantrums???

Brooke

My baby has been throwing these insane tantrums at night if she accidentally gets woken up or if she wakes up hungry for a bottle. Like, total meltdown for 15 mins at least. Out of nowhere! She has been off of formula for 2 full weeks now and strictly on cows milk. That’s the only new thing... but a big one so just wondering could that be why??
