Can children mask as young as 4? I’ve had concerns about my child and still awaiting reply from my health visitor. I suspected sensory issues with dislike of loud noises , completely distraught with handryers doesn’t like certain smells getting dressed suncream/hair wash, limited diet, obsessive interest, struggles socially- scared of other children unless knows them very well , will move away from play equipment and wants another adult by side. Worried about timings and routines. Aggressive biting shouting and scratching me at times, in public and home. Overwhelmed with busy environments, singing, loud music. Child has just started reception and I thought it would be a disaster, they’ve done 3 half days so far with half the class and my child seems to love it? has told me didn’t like the hand dryers and felt scared but just got out quickly , didn’t like the singing and wanted to shout but didn’t? I’m just very shocked are my suspicions wrong or could this be the start of masking what do I look out for?
