@Sockworkshop I am well aware my daughter's sleep wasn't normal. She wasn't a 'normal' baby in general, trouble breastfeeding, very unhappy for the first six months of life, better after she could roll/crawl/walk but still had issues - turned out it was a dairy allergy and when I stopped eating dairy and giving it to her she became a completely different child. I had gone to various GPs countless times about her crying, her wakefulness etc and was told over and over I was making a fuss about nothing, babies cry, I just needed to sleep train her, and that she was crying to manipulate me. Also when I continued to say that I didn't want to sleep train and was still concerned about how often she was waking that I had PND and should stop breastfeeding (when actually breastfeeding is correlated with better maternal mental health outcomes, and in any case I wasn't depressed, just knackered). No-one ever suggested CMPA, and when I suggested it to HCPs after frantic Googling I was laughed at, told I was being silly and a hypochondriac by proxy.
The point is, I didn't know that was what was wrong. But I knew she was too tiny to be crying by design. If i had believed what I was told, ignored her crying and just left her to scream, I would have been leaving her in pain. Just because I thought I had covered all the basis - clean, fed, comfortable - she still had a reason to be crying, whether I knew it or not. It may have taken me a while to figure it out, and I feel bad for that, but at least I can know I comforted her when she was in distress and couldn't tell me why.
And I never needed to 'teach' her to 'self-soothe' - as mentioned in earlier posts, she got the hang of it all by herself, at around 2ish. Started sending me and her Dad out of the room after her cuddle. No crying, no ignoring, no sitting downstairs listening to her call for me and eating my heart out. Just the natural consequence of her issues being dealt with, her confidence and sense of security being nurtured, and growing up. 2 years of my life having bad sleep is not to high a price to pay I don't think. Others of course feel differently or have different constraints on them that mean they have to do differently. I suppose it's possible other people's under twos are Machiavellian geniuses who cry when they are perfectly happy and just want to troll you. I don't think other people are shit (unless, as with the poster in the other thread I mentioned, they are tying up their toddlers). Just that people ascribe adult motivations to little babies when it comes to much of their behaviour, while at the same time diminishing the reality of their feelings so they can behave as if those feelings don't exist or matter. This is not the same as saying the feelings always have to be appeased or given way to; just acknowledged and dealt with.
@SipperSkipper When the Cochrane start hiring economists to do systematic reviews of medical research, I'll give Oster some consideration. As it is there simply isn't enough research to indicate the long term effects of 'sleep training' (which is a very broad church as others have pointed out, ranging from cry it out to shh-pat and everything in between, so long term effects would surely also be similarly stratified if there were any). But why are long term effects the only ones that matter? There is pretty solid evidence that being left to cry is extremely stressful for small babies in the moment. As it goes, there is no evidence that proves conclusively that sleep training improves the sleep of children in the medium term either, with there being no statistically significant difference by six years old between children who were trained and those who weren't (this bears out my own experience of a child who 'sleep trained' herself quite naturally after being an awful sleeper as a baby). Everything about Oster's MO is aimed at selling books to overextended, undersupported US mothers with minimal maternity rights and limited social safety net what they need to hear to feel better about the choices they are making in extremis. She's in it to sell books.
@EssentialHummus in that situation, I'd get down on her level and ask if she wanted a hug, if she did I'd give it to her, if not I'd stand nearby to prevent her hurting or snatching and to be available if she did decide she needed physical comfort. I'd verbalise her strong feelings for her if she wasn't in a condition to do it herself: "Wow you are really feeling angry and sad, poor you. You decided you did want that toy, but Jack has it now and it is his turn. It feels really hard when we can't have the things we want." With my daughter, this is often enough - one of the things that most frustrates her with tantrums is she can't get her words out to say what she's feeling, or if she feels like we're not listening to her - if we try and hustle her out of it she just escalates, whereas if we verbalise for her and ask if that's right she often agrees it is and starts to calm down. If it didn't work, or if she seemed like she was going to try to hurt the other child, I would take her somewhere she could have some space and continue to offer a hug from time to time. What I wouldn't do: shout, isolate, punish, or insist she stopped crying or that her crying was strategic and that she didn't actually feel how she felt. In that moment, none of those things would help her. And I'm in the game to help her understand and manage her feelings and the feelings of others, not squash them away.
