How long did your toddlers “mommy” phase last and any tips?

Amanda

My daughter is 15 months and for the last 2-3 weeks has been having separation anxiety and I can’t be out of her sight, wants me to hold her and attend to her constantly, etc. She won’t let Dad do anything for her including holding her and putting her to bed. I’m 4 months pregnant and it’s getting super exhausting. How long did this last for your toddler and any tips are much appreciated 😓
