Synch, it does take some adjusting, but once you get a routine going it is do-able. One thing to consider is that there is a big difference between a 15 week old and a baby 2 months older. By then your DS will be in a different rhythm and you will also be in a different place. I'll be honest, it probably won't be easy at first, but you are a strong, capable person and are pretty good at adapting.

I think the biggest key is planning. If you are not a "do things the night before" sort of person, this might be the time to start. The less you have to do before getting out the door in the morning the better. And it helps to have a plan for how (when) dinners will be cooked, when the best time to buy groceries is etc. Also it can be a difficult time for relationships, so having it worked out with your DH in advance about who does what is a good idea too.

I know things are difficult for you right now hun, but don't stress too much that practising isn't going the way you'd hoped. It will work out when you are doing it for real
