My DS is 9 months old. He's always been a really good baby. He can't crawl yet, he's trying, but does manage to move around the room a bit.
About a month ago he started waking in the night screaming his little head off. He's always slept through since about 6 weeks. He stops the second we pick him up.
I've now stopped picking him up but have to lean right over into his cot so my face is next to his to settle him back down. I'm 23 weeks pregnant so this is getting harder. Il pick him up as a last resort if that doesn't help after a few mins.
DH is a heavy sleeper so rarely hears him in the night and it's pointless waking him cause he's back asleep within seconds unless the baby's still screaming...his solution is pick him up, which I feel undos what I'm trying to do.
The last 2 weeks or so he's started screaming when we leave the room. He's fine leaving him with family and dropping him off at nursery. Also if there's still a person he knows in the room he may do a little grumble but is mostly ok.
I left the room for less then 10 seconds this morning, a minute after I came back he was still screaming.
I try not to pick him up but call to him from the other room and talk to him/sit next to him when I go back in.
He does it to both of us with leaving the room but not quite so piecing for my DH and will settle faster when he goes back in. He's worse for me (kids always play up for mum right)
Tried distracting him with toys, dummy, t.v games etc but as soon as he realises no one is there he starts.
I just don't know what else to try. We have another baby due in March and it's already hard to keep my house in order and get anything ready to go out on my own when I can't leave him in a safe room with his toys. I can't carry him round everywhere all day, and in March I physically can't carry a newborn and a 1 yr old. He's a big healthy boy at about 20lbs so isn't exactly light.
I'm starting to struggle to cope with the lack of sleep and the screaming. He's such a happy bubbly child when he's not screaming, I'd love to never leave him in a room without me or DH there but it's not always doable.
Has anyone been through something similar and has any hints or tips before I have a breakdown? 
Sorry for the really long post. Did not intend for it to be this long. Guess I needed to let some frustration out.
