my 3 month old is having cold from past 3 days and crying during nights and being fussy and sleeping whole day nd waking up at night

A. It could be probably because of the medicines that you are giving due to high dose of paracetamol maybe your child is sleeping well during the day and is been up and the night so check with your doctor give proper medicines which will help in healing the problem also check if your child is teething as that can also be a very big reason behind being cranky and Irritable
