Long story short, my almost thirteenth month old hadn’t been a great sleeper since around 4 months. I spent most of my maternity leave since then in a fog. I went back to work when he was around 10.5 months and my husband took over childcare at that point (we did shared parental leave). By that stage things had become a bit more manageable - waking 2 times a night and relatively easy to settle via feeding. However, things have (understandably) gotten a lot worse since he started nursery and separation anxiety kicked in - since then my husband has been unable to help with settling at night and it can take up to an hour each time he wakes. Things came to a head last week when the baby got an infection, during which he only slept on me. On Friday I collapsed from what I think must just be exhaustion. I have a very demanding corporate job and can’t go on like this, but have always taken a responsive approach to parenting so don’t want to leave him to cry it out (I know there are less severe options but believe me when I said we have tried them all to no avail). Any words of advice or solace would be much appreciated.
