It’s just jealousy my son does this too. They want the attention / love/ affection of the preferred parent. Just continue to be affectionate with your spouse and tell baby they can have a cuddle too.
My son will get between us and say stop that. Sometimes I think it's because he's seen us argue and thinks that what's going on. But either way he'll put his hands up and say stop that 🤷🏽♀️
Seems like jealousy. If it was me I'd start saying "Mommy has time for both of you. We need to share mommy. Daddy deserves hugs/cuddles/etc too. Come here and cuddle with us."
Definitely jealousy. My daughter used to pull my hubby away by his nose at that age.
My son does this too maybe not crying because of it but always tells daddy no it’s my mummy.
