My son is about to be 5 weeks tomorrow and all he wants to do is nurse. He barely sleeps long hours during the day anymore and is awake the minute we put him down?

Is there a growth spurt at 5weeks?

He also is super gassy and literally cries so often and i dont know what to do!

Also put him in the mamaroo and he cries. If I could put him down and eat i would be happy but I cant even do that and with a 2 year old toddler it just doesnt help
