I have a foster carer friend, she fosters up to 11 ish year olds, but more often she takes young ones
Moving them on can be really hard for her. Of course she is happy for them, and she never wanted to be a long term or permanent mother, which is why she chose to be a foster mum, but she has been these babies mum for up to 2 years.
I mean, she percieves herself as a carer, but her role in the babies and toddlers eyes is best described as 'my mummy' because lets face it, she does a mums job. All the caring and nurture she gives them, the little ones see her as mummy. That's something i was conscious of when bringing home my DS, who was 23 months when he came home
All babies are different, so she attaches differently to them all. Sometimes she is sad but still in a good place when they leave. But I remember about 6-ish years ago, she moved on a LO who was just over a year old, been with her since a couple of days old This LO was just a 'perect fit' for her. She really attached to LO (and baby to her as well). When LO left, she was professional around the new parents and very happy for them (as she always is), but when LO had gone for the last time, i came over to check on her and found her in a foetal position on the floor, where she had been lying for hours, just sobbing. She spent an entire weekend in bed, and took a break before fostering again. I know she still cries for this LO, 6 years later. She still has low days thinking about her. The pain is still there, and perhaps it never will. She will never forget LO, she hopes that she can come to a place in healing where she can think happily about all the good times she had with LO, rather than only the sad part of her leaving. I think she still has a little contact with the parents now. I don't believe those parents have any idea how much their DC means to the FFC. She's too professional to burden them with that - which is the way it should be, though it sounds harsh. She's never felt that way about any other LO, by the way. All LO's are different, which is why matching is so important, and an FC might feel very very differently about two different LO's
I know it was hard for my DS foster parents. They were lovely people, who acted very professionally. They were happy for DS, but I knew they would be very upset at him leaving. Luckily, intros went very well for us. Hopefully they will for you too OP
