Don't you hate it when the newborn sleepy period ends??

Why do I make babies that don't like sleep??

DD2 has been perfect so far. Goes to sleep easily and sleeps for 2+ hrs at a time. That is until the last week. Now she still goes to sleep easily for her first morning nap and actually self settles most of the time! Unbelievable compared to DD who took 2 yrs to do that so I'm not expecting it to last much longer. She will sleep for around 2 1/2 hrs. Then wake up and be happy for about 1.5 hrs when I see she is tired and try to get her back to sleep. She's harder to get to sleep for the next sleep but I finally do and then she will wake up after 15-30mins and I can't get her back to sleep. I eventually give up and try later and the same thing happens. So she's awake for the rest of the day only having 1 sleep in the morning. WTF?? This is not enough sleep for a 1 month old!!

I know she is tired. She gets cranky and only wants to be held. But she won't stay asleep!! And poo to trying to get her to sleep in her basinette instead of my arms because then she will sleep longer. Whatever. I can get her to sleep in her basinette but it makes no difference, she still wakes up!!

I could put her in the hug-a-bub but I'm too scared. I did this with DD1 and the result was that she would ONLY sleep in the HAB with me bouncing on the fitball for the first 6 months of her life. I couldn't even stop bouncing after she was asleep, had to constantly keep moving So I'm scared of having that situation again. I can't do that when I also have DD1 here to look after and spend time with.

I've been trying to start good sleep habits from the start but looks like that's not going to end up making a difference So what am I doing wrong?

Wish it wasn't so hot atm so at least I could take her for a walk in the pram to get her to sleep.
