Sleep regression during daytime?

My baby is now 3.5 months and we have issue trying to get her to nap during the day. She becomes cranky when she can't sleep and I have tried the usual way of carrying her in arms and patting her but no use. Her daytime nap was only around 30 mins each nap x 3. Does it help if we push forward her sleeping time? I'm worried she will be too tired 😫
