I got a partner. I need to wake up before the kids but I don't want to wake her up. I need gadget help!

How do you guys handle this?My partner hates it when I set the alarm on the phone because it wakes her up. She doesn't need to "get woke" any more than absolutely necessary with a 4 month old but I got stuff to do.Any good wearables on the market that I should get for this situation?I'm thinking some that vibrates on my wrist that's strong enough rouse me out of slumber, but quiet enough let her sleep.I got an Andriod phone. Thanks in advance. via /r/Parenting http://ift.tt/2od3XmU
