HI Marilyn,
Being a new mom is very overwhelming, so big HUGS first of all. You are doing a remarkable job so far and should be very proud of yourself! I will try to answer most of your questions as best as I can.
First, being that Nathan is so young, I would try to stick with a 45minute-1 hour MAX awake time for the time being. So if he takes 30 minutes to feed, then literally spend 15 minutes doing a diaper change and walking around the house-very lowkey and keep it simple. The thing to remember that to a 6 week old staring at you and a diaper change is an activity!
SO that is my first piece of advice.
Is this o.k? I know Tracy says to only do single side feedings
The book is just a guide. I think you have to do what feels right and comfortable for you and your lo. The main objective for single side feeding is to make sure the lo reaches the yummy filling hind milk that comes after nursing for 10-15 minutes. If he seems to have emptied you out, and he still seems hungry, then by all means offer the other breast.
Also, we tried cluster feeding at 5 and 7 or 6 and 8. But that turns out really bad since he is so hard to put down! So we basically spend the hour he should be sleeping putting him down to get him up to feed right after! Do we really need to put him down or could we just do E at 5 then bathe him, then go straight to nursing again after his bath and then straight to bed?
Of course! Again, do what feels right for you and your lo. We really only did cluster feeding during growth spurts (6 weeks, 12 weeks). The rest of the time the DF was enough to help her get through the night.
Is there anything I need to change or start doing???
Relax and enjoy your lo right now! The independent sleep/pat-shush/routine will all start to fall into place with every passign week. My biggest regret was that I spent the first 9 weeks of Taylor's life completely stressed about her routine and teaching independent sleep, and in the end everything worked out beautifully! Just remain calm and try to be as consistent as possible. Lo's thrive off of routine and consistency, so that is one of the best things you can do for him.
Please let us know if you have any other questions.
