I'm looking for a bit of advice about DD who is 15 months old. In terms of her development she is meeting the relevant milestones (walking, saying a handful of words, interacting with us) with no concerns in that respect, and she's generally a happy little girl.
I'm increasingly worried about her attachment to me, and don't know if I'm worrying over nothing. I went back to work full time when she was 8 months, which was really hard as we were barely apart during my maternity leave. I was luckily able to go part time when she was 11 months. When I'm at work she is cared for by my PIL.
DD has never, ever cried when I've left her, and when I pick her up she actively ignores me, not making eye contact etc for at least an hour. She will happily go to MIL and enjoys spending time there (always playing happily when I pick her up), but equally is not outwardly pleased to see her. She is the same if DP drops her off or picks her up.
On my days off (and after DD has warmed up to being at home) DD is happy, interacts with me, will shove books at me to read, play with toys with me, brings me cuddly toys, will cuddle up to me at times etc. When we go out to soft play or baby groups she is cautious when taking everything in, but then will interact and explore confidently. At home she doesn't get upset or concerned when DP or I leave the room, and if she follows it's more out of curiosity than anything else, sometimes she will happily carry on playing with her toys.
I'm worrying because I know from friends that their toddlers are normally really pleased to see them at pickup, and no one seems to experience the 'ignoring' that I describe. I have stupidly started reading about attachment theory and am really concerned that DD sounds an awful lot like avoidant insecure attachment in terms of her behaviour when I leave and return.
I hate thinking this, but could something be wrong? Could it have been my going back to work (before we were both really ready)? Or am I worrying about nothing?
I know in the grand scheme of things there are a lot worse things, and think I might be being silly, but I keep worrying and it's eating away at me a bit, so wanted to ask. Thanks for any words of wisdom!
