3.5 month LG here. She'll also only nap on me, & hates the bouncer & sling. Rough schedule:
730 -wake, feed, she chills on the bed while I get dressed then I change & dress her
830 - she sits on one of us or goes on the playmat while we eat breakfast.
915 - I sing her songs, maybe another feed, pre-nap fussiness
10 - nap, i watch TV
11 - wake, feed, more songs, some sensory play (flashcards, foil blanket, ribbons, different fabrics)
1230 - she sits on one of us or goes on the playmat while we eat lunch, then has a feed before we go out
1 - walk out in the pram, she naps
2 - home, feed, more songs, up to 20 mins of cbeebies or a sensory video, more bloody songs, maybe some more sensory play if she's up for it. Some days she goes in the sling and I cook/bake/clean.
430 - feed, nap, I watch TV
5/530 - pass her off to DH if I can while I cook tea.
6 - bath, massage, book, boob
7 - 10 - attempting to get her to go to bed with increasing levels of desperation.
We're starting Mon & Weds AM baby classes next week which should mix it up a bit too. She often has a longer early afternoon nap & misses the later one, which isn't great.
