Long, sorry, but don't want to drip feed.
Until my twins were about 15 months old, I was convinced they didn't like/need me. They were totally content by themselves and rarely cried. They didn't like being held or making eye contact, and just weren't interested in interacting with me at all really. They didn't seek me for comfort and they had never even tried to hand me a toy. I must add, I did not have PND and am confident that it wasn't just my perception. My (excellent) health visitor spent two hours at my house and agreed that their presentation was "unusual". I found it all a bit upsetting, but of course I kept trying every day and made sure that all their needs were met.
Overnight they changed, and almost the opposite happened! They wanted to involve me in all of their play, finally started responding to their names and their language exploded. They also developed huge separation anxiety, which did not concern me as I know it's quite usual. Strangely, they still didn't really like affection though.
However, they are now 2-and-a-half, and they are still like it (more than a year later). If I so much as leave the room to use the toilet, they scream like I'm leaving them forever. I try to be as attentive as possible, but it's exhausting and I worry that I've failed them somehow. Despite my best efforts, they won't nap anymore so I have no time during the day to safely cook or get housework done. This means I do unfortunately have to ignore them briefly while I do things like prepare food or get dressed in the morning. They literally cling to my legs all day, yet if I try to get them to sit on my lap they won't have any of it. They fight for my attention constantly, but when they get it they don't really want it. It's like they just need to know I'm there.
I feel like they're not well attached to me. I'm really worried that I've done something wrong. How can I fix it?
