Night waking for Carina

Carina was sleeping thru the night untill 2 days ago. She started waking up every 2 hours the first night and she cried for 2 hours last night. I knew she is teething. I gave her tylenol and the ora gel. Didn’t help much. I’m drained out coz I had to deal with Colton during the day for his potty training and deal with Carina for her night waking. I basically didn’t sleep at all. They usually take turn for nap with means that I got no time to rest during the day. Isn’t that the nicest part of being a mom?
