My 13mth does exactly the same! She had a meltdown yesterday because I wouldn’t let her eat dirt from the ground. She also has another one as she didn’t want to go in her car seat. Arched back, ridged arms, throwing her body around, tears and OMG, the high pitched screaming… totally normal!
This is what she’s like at the minute. Just so angry and screaming at everything. I kept thinking of adhd because she can be absolutely fine before / after. As in laughing and being cheeky to then a full on melt down 🤯
This is normal toddler behaviour. I wouldn't jump immediately to ADHD. My 14mo keeps having meltdowns because I won't let her walk around with food and water.
