Ahhhhh not wanting sex as often

Hi!

So my husband and I have known each other for 5 years now, and have recently got married 2 months ago! We have two children, a 2 year old & 4 month old.

The first year of being together we would constantly make love...like pretty much 5x a day. Now, I have absolutely no desire. Is this normal? We are both 27 years old. Idk if I lost my sex drive after pregnancy, but I feel terrible because he wants it alllll time time and I’m just not feeling it. I’m exhausted, and don’t get excited like I used to. Has anyone else experienced this?
