Lei Lei,
I had been through that. My husband complaint that I didn't care about him, never show care for him, that I only care about my son. And I got frustrated with him when he wanted to chat with me or wanted to get intimate with me. I was anxious that my son would wake up from nap and I had not finished the housework. Work stress and lack of sleep did not help. Lots of quarrels and tears.
But Love will pull you through.
I learned to relax and let go. Leave the clothes unfold, do simpler cooking or eat out and rearrange my time and priority.
Your husband is also trying to adjust. Allow him to help out in taking care of your child, so that he doesn't feel left out.
Relax and let go of unneccessary worries. The house can be dirty and messy, what is important is the people living in it are happy. Give him more hugs and kisses. He just need to know you still care about him.
He definitely yearn for your attention, and that means he loves you A Lot!
