I need some motivation...

Feeling overwhelmed. I feel like my house is getting messy even though I am cleaning every second that my LO is content. He is 1 month old and just the past couple of days has become a stage 5 clinger and if he doesn't have my full attention (holding, nursing, attention, etc) he is extremely fussy and will start crying. He also doesn't sleep more than a couple hours through the night. I just need someone to tell me that it gets better. I love him. I love being a Mom. I just need some assurance that this is normal for the first month and when am I going to see a light at the end of the tunnel??
