My baby is 15 weeks old and for the last few weeks has mainly only been napping for about half an hour at a time. She used to do a nice long morning nap of about two hours but now rarely sleeps that long in the day. She’ll happily sleep in sling, swing, pram, crib, but none of them for very long. Bouncer doesn’t do it for her. Means she needs about four to five naps a day to make it comfortably to bedtime which is fine but doesn’t give me much chance to get anything done and I feel like I spend half my day trying to coax her to sleep. She’s usually happy enough when she wakes up but sometimes still yawning. Is there any way I can try to extend them? Or should I even be bothering and just accepting it for now? (I’ve read they don’t tend to consolidate naps til about 5 months old). Could this be part of the 4 month sleep regression? She hasn’t been too bad at night (touch wood) but then we have never really had long uninterrupted stretches. Four to five hours, tops, at the start of the night then waking every two to three hours after. That’s actually an improvement on a couple of weeks ago... 
Any advice or insight appreciated.
