Sleep regression?

Courtney • Jaxon 💙

My baby is 4.5 months old and the past 3 nights he’s up every 2 hours! Even during the day his naps are only 45 minutes long. We’re so exhausted and I feel like we’ve tried everything. We feed him and play with him as much as possible during the day and he’s still not sleeping. Is this the 4 month sleep regression? Any tips on getting through it?
