Hi , some thoughtful information and great ideas on here.
I do think all children are individual , our lo is 2 years 1 month and has been with us for 1 year 3 months.
I'm returning to work 20 hours next week after 15 months off . my lo has been attending nursery for past 6 weeks starting with 3 hours 1 day a week and working up to last 2 weeks the full 20 hours.
All I can say to the op is that what we want for our lo will always be the best we can give , cant always make it perfect .
I would love to be a sahm but that isn't possible .
I have done my absolute best to support lo for the year we have been off together and "fingers crossed" she seems to love nursery.
I was also very aware of attachment but I can also say I have a bc who never cried when I left her at minder / school, I know she didn't have disruption like a ac has but I was worried that I had done something wrong because she didn't miss me at all. I mentioned this to a work colleague ( child psycologist) who said that she was probably so attached that she was confident away from me and that I would return. Now she is 8 we have a lovely relationship and she is a happy confident and loving child , so maybe he was right.
Back to my ac , she was a little fretful when first left at nursery so she had a familiar person meet her and they would offer her some breakfast , good distraction ! loves food ! I also made a book with photos of her family (us) land a soft doll she loves. nursery tell me she she would kiss the photos of us and they would talk to her about "mama coming back later"
I also never say bye , always say "see you later" . when I go to pick her up she gets over excited and runs around like a dog chasing her tail.
My heart nearly burst last week when after her "run" she ran to me for a squeeze and then went to all the adults saying " look , my mama , my mama"
The next day she is asking us if she is going to nursery and smiles when we say its a nursery day.
Despite her being an ac she is becoming confident and happy with others while still preferring us , her family.
Hope it goes well, dont feel guilty about doing your best
best wishes
