Waking up after putting baby to sleep

Hi all,

My little boy is 7 months old on the 11th, he’s breastfed but been on solid food for a month now. I had some sleeping problems with him waking up every hour and not going back down, so me and my husband decided to put him in his own room, it’s been so much better, he’s even sleeping through the night. Omg it feels amazing to get sleep finally 😂

I’m just wondering if anyone has experienced the following- I put my son to sleep in his crib at his bedtime, between 6 and half 6... then almost exactly 40 minutes later he wakes up, and it usually takes about an hour to resettle him. It’s abit exhausting at night and I don’t really know what’s for the best, my friend said the thinks she remembers her daughter doing the same at my sons age.

This is his routine (it can vary)

Awake 6am,

Breakfast 7am

Nap 10am- 1pm ( I don’t know why but he tends to have his full 3 hour nap in one go)

Evening meal 4.30pm

Bath and bed for 6pm

Any suggestions welcome

Thank you
