I completely understand that as a single parent to an only child you are totally wrapped up in her life, you have sole responsibility for her upbringing and care, and you are together every waking moment, and love it. It is for these very reasons that you have to let her join in with the other children at nursery/pre-school. She will soon get to know that mummy drops her off, she has fun with her friends, learns to play with other children, sharing and taking turns, take part in messy play (which you might not want at home!), she'll learn what it's like to be around other adults, how to be kind to one another, there are so many benefits. While she is there you can have meet ups with friends for coffee and a chat, or sit and read, have a relaxing soak in the bath, go for a swim without having to constantly have an eye on your daughter, do some gardening, go to the hairdresser's or have a massage, anything that takes your fancy where you can be you and not mum. The excited look on her face when you pick her up and proudly gives you a piece of artwork or a cookie that she's made is priceless. Her friends will become important to her and it will be a completely different relationship to the one you have with her, she'll get invited to birthday parties and maybe play dates, you'll get to meet other mum's and either build friendships yourself or keep yourself to yourself, it's up to you. Fast forward when she goes to primary school to reception, she'll have experience of you dropping her off, she'll know she hasn't been abandoned and that you will be there to pick her up when school finishes, she'll have got used to sharing, taking turns, being quiet for reading time, queuing up etc., there are so many benefits of having been to nursery/pre-school. I hope you will consider it, it will be good for both of you 🙂
