Hi all. Just wanting to know if this is normal...

Hi all. Just wanting to know if this is normal. My 13 week old son is feeding every 2 hours during the day and only sleeping for 45 minutes in between feeds. I have tried dragging it out but he is very unsettled until I put the boobs out. He was fine before his 12 week growth spurt sleeping up to 3 hours between feeds but since then he is a nightmare and I am slowly going insane being stuck to the couch and my 4 year old is being ignored. If it is normal does it get any easier. Thanks.
