Hi,
I am a single mum to a 5 month old and a nearly 3 year old and have been single since I was about 4 months pregnant.
I think one tip I learnt early on is Cbeebies is your best friend... There have been so many moments when baby has needed a feed or to go down for a nap and I can leave my 2 year old to watch cbeebies while I quickly put baby down upstairs.
Try to organise your home so that you wont have to flit from room to room to get things, I keep nappies and wipes both upstairs and down now as I kept having to pick baby up and move her and toddler to wherever the nappies and wipes were (after spending a good ten mins searching for the wipes!)
Try to get your DS to help you when possible, little things that mean when your feeding baby you wont have to keep getting up (in my case the tv remote lol).
Every week I get myself something that is just for me. The last few weeks I have been getting books and will sit and read when both the girls are asleep. Just something that isnt child orientated really, to give myself a bit of a break.
The first 6 to 8 weeks were the hardest for me, now I have learnt how to juggle having the two of them and I really enjoy being a mum.
I am 21 and have absolutely no family or friends whatsoever to give me some support....if I can do it then I bet you can too!
Good luck and congrats.
