Hey! Haven't got kids myself , but a pal of mine is just completing her PhD, and she has two kids, who were 3 and 7 when she started, and she is a single mum to them. So it certainly can be done- she has done phenomenally well and is due to finish almost within three years, and with publications and conference presentations and teaching experience as well! I know it has been really tough for her at times, but it just goes to show it can be done with a bit of planning and a lot of organisation! So good luck and congrats on being accepted onto your PhD! Best, KB
