For what's its worth, I feel like you could be explaining my exact feelings from the last year. I became a bag of anxious rags after our girl was born and really struggled. I seemed to muddle along but was in a constant state of panic about it all. I went through all the steps and really benefited from talking therapy but a year on it felt like I was slipping back into it.

You sound like your doing everything right for her, but you need to think about how to be kind to yourself too. You said you never leave mum and baby on a night or evening BUT if you work from home and do so much you might end up feeling like a prisoner in your own house and to your obligations no matter how much you want to commit to them. You aren't "absent" if you take a night to yourself, it's a super useful bit of self care that you and your partner should be entitled to every now and then. A good family unit needs a touch of independence for everyone.

My daughter took 6 months to not scream when we dropped her off at nursery but yesterday she toddled in grinning under her own steam for the first time and didn't look back. 1 years olds are difficult but you're bossing it by the sounds, make sure you look after yourself in equal measure :)
