How much sleep should a baby be having in the day? DD is 18 weeks old and is sleeping really well at night, up to about 11 hours from 7pm to 5.30/6am. She's up, feeds, plays, feeds again and will go for 30 min nap. After that, she seems to refuse to go back to her bed for the rest of the day. I put her down asleep after lunch time nap and she's awake before she even hits the mattress - I've been trying controlled crying the last couple of days completely unsuccessfully - going in every 5 to 10 mins for a whole hour and giving in cos it's breaking my heart to hear her cry for such a long time. then if I go out in the car, she's asleep before we're down the drive! But some days I wish we could just spend the day at home, or its raining so I can't go out with the buggy - but if she doesn't have a lunch time nap she's too tired to play and enjoy which also upsets me cos she just doesn't seem happy. I'm at a loss for what to do - I can't get anything from other mums in the monday group I go to cos they think I'm so lucky she's not up in the night but the day times are just so exhausting and I feel she's missing out cos she's so tired by lunch time... should I persist or am I doing her damage by letting her cry. I kinda feel like I've maybe made things worse by trying and giving up the last few days by picking her up and bringing her downstairs when she's not had a nap and cried for an hour...
