Older child is extra clingy?

Fei

For those who are having their 2nd, is your older child extra clingy? Our 19 mo old used to let her dad put her to sleep, nap, etc. She still loves playing with him during the day but she only wants me when it’s bed time or needs comfort. It’s getting harder as tummy gets bigger. It’s like she knows change is coming and worries mommy to leave her. What are you doing to prepare her?
