Postpartum depression

Is it possible to get postpartum depression now? My baby is 10 and a half months and in the first few weeks of her life i had the baby blues really bad and felt so out of touch which my environment but then it settled down slowly and I was alright especially as I stopped breastfeeding which meant the demand for feeding was shared with me and my partner so that helped a lot.

but now my partner has started working and I’m completely alone with baby and today was the first day and I was alright all day but suddenly after I gave her dinner I started to feel bad and I feel really out of touch with my environment again and really teary. Also my mum’s mum had really bad postpartum depression with her babies and had to be hospitalised so I’ve always been worried
