DD is 7.5 months and her afternoon nap is a nightmare and getting worse. She sleep very well at night although still wakes up once for a feed (breastmilk). She usually wakes up between 7:30 and 8am and after having breakfast she will go back to bed for a morning nap two hours after she woke up. She will sleep for 30 or 40 minutes. She has never slept longer than this in the morning.
Our problem appears in the afternoon. She has lunch at 1pm and after lunch she goes to bed. Today she is still in bed complaining after 30 minutes nap ONLY. I am running out of ideas of what to do to make her sleep for longer. TBH I just don't knopw what else to do. I have let her cried, I have sleept with her (it is the only way of getting her to sleep 90 minutes). I know she can sleep for at least 90 minutes because she has done it with me but she won't do it on her own. I have tried laying by her side. Please give me more ideas of what I can do to improve her afternoon nap.
She has dinner at 6pm, bath at 7pm and then she has BM and goes to be at around 7:40pm with no problem at all.
Any advice will be much appreciated. Thank you in advance
