For about 8 months now my daughter has been obsessed with a particular princess. She reenacts the story several times a day and turns almost conversation around to talking about it. We went to a toddler group today where the theme was Sports and I was expecting her to want to talk about it afterwards, but instead she was talking about a theme they had several months ago with a very vague connection to this princess. She has some princess dresses but won't wear them because they don't closely resemble that of this particular princess. She lets me read other books to her but isn't particularly interested in talking about them after. I've tried showing her other films but she cries and only wants to watch the one about this character. It's not that she's been socialised to like this princess.... I find it a bit tiresome and try to encourage other interests, but she is laser focused. None of her friends are into it so it's not that. It's completely her own obsession.(She doesn't attend any childcare).
I don't mind too much. It's sweet and endearing, if a bit tedious, but I'm a bit concerned that this level of obsession might be a sign of ASD (which is very strong in my family). She has good social skills and eye contact so no other concerns apart from obsessiveness on this particular subject.
Do you think it's concerning or am I being ridiculous?
