5 week old bub is very alert for the first waking feed (around 8am) and won't go back to sleep after the eat/play time. She will fight her tiredness and stay awake even if I leave her on the play mat and do my own thing. By 2 hours awake she will start to get agitated then cry because she is too tired, but she won't sleep unless I pick her up and rock her to sleep. Even if she is lying on the mat calmly and I pat her and wrap her up she won't sleep. The early childhood nurse says rocking her to sleep can create bad habits but didn't suggest anything else I can do.
Is it really a problem at this age, and can anyone suggest what I can do to help her settle? Sometimes she catches up on her sleep after the next feed when she'll sleep after feeding (another bad habit the nurse says) and leave out play, but if she doesn't she is so antsy for the whole day.
