Answer: This sounds like a classic case of separation anxiety. If she is well and thriving and you’ve no reason to suspect she’s sick then it may well be separation anxiety which is very normal for this age and stage. She’s learning without a shadow of a doubt who is best placed to meet her physical and emotional needs. Mostly this is the mother and this is not an indication that she doesn’t like your partner, just that she loves you and wants you to be close to her because you help her to feel safe. This is so important in the first few years of life. Don’t see this behaviour as her being naughty or spoilt, in many ways it’s a sign of what a great job you’ve done so far in helping her to feel safe and secure.
Give her lots of cuddles and reassurance but don’t limit your partner’s access to her. She needs to be cared for by him as well and he will teach her things that you as a mother cannot, eg, what a good man is and how to relate to other people in the world, not just mum.
She will grow out of this stage but give her time. She is still so little.
