Am I changing too much all at once? Im back to work at the beginning of March so need some improvement before then! How do I tackle getting him back in his cot? For naps he again started there but wakes after 30/40 mins - do I try to resettle and put him back in his cot?
I don't think so. I mean if you want things to change, you need to change them right?! Easier said than done, believe me, I know. I would start by working on the day time for a week to 10 days, and then tackle nights. I think it's a little less daunting on all accounts if you do one thing at a time.
So, all naps in cot, resettling and keeping him in the cot. His A times may need a bump again if he's continually waking at 30/40min. At night, I would resettle until you go to sleep and then if you need to for the first week, bring him in with you. Ultimately, though, you are going to need resettle and keep him in the cot if that's where you want him to sleep.
(((Hugs))), it's so hard to be so tired. Do you have some help you can secure so that you can get a break here and there during this time?
