No sex - it’s been two year :( tips to seduce my husband

Had a baby last year in may - it was just us and we managed it ! We both helped each other a lot through out the year- he cooks , he clean - he does everything! But it’s been a year more than a year we haven’t had a sex - hmm nothing !! We didn’t even try- when I asked him like you don’t even come near me - he is like he is drained out plus our baby is sharing a room with us !! So yaa - no sex !! I have been like this cold since two year ! Husband is nice - I am sure he is not cheating I checked his phone too! Also we have been fighting a lot these days - can anyone help me ! What should I do to seduce my husband ?
