My daughter who is a new mom, her baby 2.5 months old, lately she's been acting kind of strange? I've noticed, she comes home from visiting her friends, etc. and often seems very on edge, and very wired... or so it seems? She has a history of drug use.. in past... before the baby... but now I don't know if she's just stressed out or what? But we get into it allot because she often seems so hyped up or anxious, fast movements, and doing things that just don't seem right? But when I try to confront her ot ask her to please relax or calm down she gives me this crazy look, and we get into it... she says that I'm making her nervous by standing over her... or watching her etc... and I'm like omg... im not doing anything mean or trying to make you feel nervous... and I'm not... I'm just trying to help, with the baby, help calm him etc... while she changes his diaper etc.
I feel like I can't do nothing, or say anything without her getting all on edge, or moody or crying etc.. So I don't know? What to do...
As far as I know she's been off drugs sense she got pregnant. And I hope she hasn't started using again? I don't think she is? But I don't know?. just something doesn't seem right, past few weeks. And I worry about my grandbaby sometimes... I know she would never intentionaly do anything to hurt him or scare him. But she's just sooo wired acting and doing things fast... and sometimes waking him up when he's asleep to play with him? Just weird... not normal type things? Or to me its not.
IDK maybe I'm doing crazy...
But she lives with me... and I know how she normaly acts when she's not messed up or on something. So I do notice a difference

Now she recently got on birthcontrol... the kind they put in your arm that last 3 yrs. And she got somewhat depressed after that... but then it seems she's OK... but now this... so I don't know?
Geesh I could be over reacting... and maybe she's just adjusting to the birthcontrol, and stressed out... due to prob with her boyfriend... etc...
Plus she is on probation for DWI from almost two years ago still...
So she she's her PO every month... but she did fail a drug test way back before she got pregnant. She tested positive for meth I think? But her main drug of choice back then when she was using was prescription pills... and weed, and alcohol.

As far as I know the only thing she does now is smoke cig. Not in my house though...

Just need some advice... or others opinions..
As I don't want to jump the gun, and she gets mad and hurt and very defensive when I even hint that she might be using again? So I don't know... maybe I'm wrong... but just something doesn't seem right.

Thanks..
Worried and stressed new gramma ( this is my first grandbaby)

She could be suffering from post partum depression; but some of the symptoms don't match up. I hope she is not breast feeding and doing any drugs, that would harm the baby.

Maybe you should try and just back off for a bit, maybe you are making her nervous because you are over anxious about her past drug and alcohol abuse.
Backing off a bit may be difficult for you, but try it out and see what happens. As long as you know where the baby is, you won't have to concern yourself too much.
