We planned DD as an only, and we will be sticking with it. It is something we have discussed, but between finances and career issues, it just seems impossible. I know many people say: just go for it, you'll manage somehow. But I can suffer quite badly with anxiety, and I'd not manage. I'd rather stick to one and enjoy her than have two and spend my entire life so stressed that everyone feels miserable.
We would also need a bigger house, but can't really afford one where we live. Having two would also have a major impact on my career, and although it probably sounds incredibly selfish, I adore my job, I've worked bloody hard to get where I am, and it is not the kind of job where you can take time out. If I did, even just for a couple of years, my career would be totally over. Plus I am the majority earner in our house.
In other news, we are slowly moving towards getting rid of DDs daytime nap. She was becoming a nightmare at bedtime, so we've cut her nap down to 30 minutes, and all is good again. She will be moving up to pre-school in September, and I think by then she will have dropped it totally.
We've booked a holiday in the sun in June, and I can't wait! DD is getting easier and easier now, and I think this will be our first proper relaxing and fun holiday! No need to lug about nappies and bottles and special food - it feels so strange just being able to walk out the house without five tonnes of crap. DD has a little back pack that I always keep stocked with wipes, tissues, spare kickers and leggings, drawing bits, a carton of juice and snacks, so I can just grab that and go! 
DD doesn't have too much screentime, but that is mainly because she is full time at nursery! During the week she normally watches something for about half an hour when she wakes up. If she is knackered she will sometimes watch a bit when she gets home, but at the moment she is far more interested in helping Daddy to water the garden. She is also a bookworm and turns the TV off when she wants me to read to her! At the weekend she watches a bit more in the mornings, but by 10am we are usually out and about for the rest of the day. She rarely uses our iPad, unless we are on holiday. When she does it is mainly to Skype with people, or she has a couple of games she is allowed as a treat if she's good.
So pleased things are going well for you green
